### PARTIAL OUTPUT (time limit hit; the model was still generating) ### === thinking so far === Let me plan the data cleaning and compute expected numbers carefully. Parse CSV: rows with quoted fields containing commas. Duplicate order_id 1008 appears twice (rows 1012 and 1017 in file) — keep first, drop second. Rows: 30 data rows total (after header). Duplicate dropped: 1. Rows excluded (non-numeric amount): 1006 (N/A), 1028 (N/A), 1017 (unknown) → 3 excluded. Rows counted: 30 - 1 dup - 3 excluded = 26. Wait — duplicate 1008 is dropped first, then excluded rows counted among remaining? Rows received = 30. Duplicates dropped = 1. Excluded = 3. Counted = 26. Now parse amounts (strip $ and commas): Regions normalization: Texas/TX/tx/texas/california/CA/California → Texas/California; Ohio/OH/ohio → Ohio. Dates → quarter: Jan-Mar = Q1, Apr-Jun = Q2. All dates are 2025. Let me list all rows with cleaning: Q1 rows: 1. 1001, 2025-01-06, Texas, 1240.00 2. 1002, 1/9/2025, California, 980 3. 1003, 2025-01-14, Texas, 312.50 4. 1004, Jan 21, 2025, California, 1764.00 5. 1005, 2025-01-27, Ohio, 455 6. 1006, 2/3/2025, Texas, N/A → excluded 7. 1007, 2025-02-10, Ohio, 1102.25 8. 1008, Feb 14 2025, California, 2310.00 (first occurrence kept) 9. 1009, 2025-02-18, Texas, -450.00 (refund, negative revenue) 10. 1010, 2025-02-24, Texas, 870.10 11. 1011, 3/3/2025, Ohio, 1999.99 12. 1012, 2025-03-08, California, 640.00 (dup 1008 dropped) 13. 1013, Mar 12 2025, Texas, 1580.00 14. 1014, 2025-03-19, Ohio, 225.75 15. 1015, 2025-03-27, California, 3050.00 Q2 rows: 16. 1016, 4/2/2025, Texas, 990.00 17. 1017, 2025-04-07, Ohio, unknown → excluded 18. 1018, Apr 11 2025, California, 1420.50 19. 1019, 2025-04-16, Texas, 2075.00 20. 1020, 2025-04-22, Ohio, 760.25 21. 1021, 5/1/2025, California, 1111.11 22. 1022, 2025-05-06, Texas, 845.00 23. 1023, May 13 2025, Ohio, -220.00 24. 1024, 2025-05-19, Texas, 1300.00 25. 1025, 2025-05-28, California, 2940.40 26. 1026, 6/4/2025, Ohio, 515.00 27. 1027, 2025-06-10, California, 1875.25 28. 1028, Jun 17 2025, Texas, N/A → excluded 29. 1029, 2025-06-23, Ohio, 1660.00 30. 1030, 2025-06-30, Texas, 730.90 Now compute revenue by region × quarter. Texas Q1: 1240.00 + 312.50 + (-450.00) + 870.10 + 1580.00 = 1240+312.50 = 1552.50; -450 = 1102.50; +870.10 = 1972.60; +1580 = 3552.60. Texas Q2: 990 + 2075 + 845 + 1300 + 730.90 = 990+2075=3065; +845=3910; +1300=5210; +730.90=5940.90. (1028 excluded) Texas total: 3552.60 + 5940.90 = 9493.50. California Q1: 980 + 1764 + 2310 + 640 + 3050 = 980+1764=2744; +2310=5054; +640=5694; +3050=8744.00. California Q2: 1420.50 + 1111.11 + 2940.40 + 1875.25 = 1420.50+1111.11=2531.61; +2940.40=5472.01; +1875.25=7347.26. California total: 8744 + 7347.26 = 16091.26. Ohio Q1: 455 + 1102.25 + 1999.99 + 225.75 = 455+1102.25=1557.25; +1999.99=3557.24; +225.75=3782.99. Ohio Q2: 760.25 + (-220) + 515 + 1660 = 760.25-220=540.25; +515=1055.25; +1660=2715.25. Ohio total: 3782.99 + 2715.25 = 6498.24. Column totals: Q1 total: 3552.60 + 8744 + 3782.99 = 18079.59. Q2 total: 5940.90 + 7347.26 + 2715.25 = 16003.41. Grand: 18079.59+16003.41 = 34083.00. Check region totals sum: 9493.50+16091.26+6498.24 = 34083.00. ✓ Top region: California, $16,091.26. Now build the HTML. I'll embed the raw CSV as a string and parse it in JS, implementing cleaning rules, computing pivot, drawing SVG bar chart, data quality panel, headline. Should be computed in JS rather than hardcoded — the user says "The numbers displayed must be computed correctly from the data" — compute from data in JS. Good. CSV parsing: handle quoted fields with commas. Write a small parser. Amount parsing: strip $, commas, whitespace; if empty or "N/A"/"unknown" or non-numeric → excluded. Negative allowed. Region normalization: trim, lowercase; map: tx/texas→Texas, ca/california→California, oh/ohio→Ohio. General rule: handle these specific ones. Date parsing: formats: 2025-01-06 (ISO), 1/9/2025 (M/D/Y), "Jan 21, 2025" (Mon D, Y). Parse month, determine quarter by month 1-3 → Q1, 4-6 → Q2. Design: dark dashboard? I'll do a clean, refined light design with strong typography. Use a distinctive font — system fonts only since no external libraries... wait, "no external libraries" — Google Fonts are external resources, arguably not libraries but I'll stay self-contained: "no external libraries, everything inline". So no external fonts. Use font stack with nice serif/sans combos available locally: e.g., "ui-monospace" for numbers, Georgia/serif for headline? I could use a tabular numeric display. Use system font stack but craft typography carefully — letter-spacing, weights. Design idea: a "financial ledger" aesthetic — off-white paper background, ink-dark text, monospace numbers, a red accent for refunds, thin rules. Pivot table with monospaced right-aligned numbers, totals row/col shaded. SVG bar chart horizontal bars with labels. Data quality panel as small stat strip with counts. Signature moment: the bar chart with refund bars shown in red hatch going left? Actually revenue by region could include refunds already netted. Could show gross vs refunds? Keep simple: bar chart of net revenue by region, with a small marker for refund count maybe. Keep it simple but polished. Layout: single column, header with headline at top (headline #4 — one-line statement), then quality panel (4 stats), then pivot table and bar chart side by side or stacked. Actually headline should be prominent at top. Let me write the code. CSV string with backticks. Parse lines respecting quotes. Parser: ```js function parseCSV(text){ const rows=[]; let row=[]; let cur=''; let inQ=false; for(let i=0;ir.length>1||(r.length&&r[0].trim())); } ``` Then header row skipped. Amount parse: ```js function parseAmount(s){ const t=String(s).trim(); if(!t) return null; const cleaned=t.replace(/[$,\s]/g,''); if(!/^-?\d*\.?\d+$/.test(cleaned)) return null; return parseFloat(cleaned); } ``` Region: ```js function normRegion(s){ const t=s.trim().toLowerCase(); if(t=='tx'||t=='texas')return 'Texas'; if(t=='ca'||t=='california')return 'California'; if(t=='oh'||t=='ohio')return 'Ohio'; return s.trim(); } ``` Date → quarter: ```js function quarterOf(s){ const t=s.trim(); let m=null; let mm; if(/^\d{4}-\d{2}-\d{2}/.test(t)) mm=+t.slice(5,7); else if(/^\d{1,2}\/\d{1,2}\/\d{4}/.test(t)) mm=+t.split('/')[0]; else{ const mo=t.match(/^([A-Za-z]{3,})\s+\d/); const names=['jan','feb','mar','apr','may','jun','jul','aug','sep','oct','nov','dec']; if(mo){ mm=names.findIndex(n=>mo[1].toLowerCase().slice(0,3)==n)+1; } } if(!mm||isNaN(mm)) return null; return mm<=3?'Q1':(mm<=6?'Q2':(mm<=9?'Q3':'Q4')); } ``` Cleaning loop: track seen ids (Set), counts. Exclude if amount null. Note: dedupe rule first — keep first row regardless of amount validity. Order: iterate rows; if duplicate id → dropped++, skip; else parse; if amount invalid → excluded++, skip (but still not counted); else counted++. Careful: "keep the first row and drop the rest" — even if first is N/A? Here 1008 dup is valid anyway. Mark id as seen when first encountered. Pivot: regions fixed order: California, Ohio, Texas (or by total). I'll order regions alphabetically or by discovery. Use sorted order: California, Ohio, Texas. Quarters: Q1, Q2 (only present). Format dollars: `fmt(n) = '$' + (neg?'-':'') + abs.toLocaleString(undefined,{minimumFractionDigits:2, maximumFractionDigits:2})` — careful with -0.45; standard. SVG bar chart: horizontal bars, scale to max value (California 16091.26). Bar height ~36, labels region left, value right of bar or at end. Width computed. Add grid baseline. Show negative handling? All region nets positive, fine. Headline: "Top region: California — $16,091.26 net revenue across 13 orders" — must be one-line stating top region and its total. Compute dynamically. Data quality panel: rows received 30, duplicates dropped 1, rows excluded 3, rows counted 26. Maybe also refunds count (2: 1009, 1023) as extra insight — allowed, panel must show those four; I can add refund count as bonus. Keep the four required prominent; add "refunds netted: 2" small note maybe. Fine. Visual design: Let me go with a paper/ledger look: - Background: #f4f1ea (warm off-white). - Text: #1a1a17. - Accent: #b3350e-ish (burnt orange) or deep green #2d5a2d? Ledger red for negatives: #c0392b-ish. Accent: #0f4c3a dark green? Choose a restrained palette: ink #171613, paper #f5f2ea, accent crimson #b03427 for refunds/excluded, and a deep teal for bars? Bars in ink with one highlighted (top region in accent). Hmm. Fonts: headline serif — use "Georgia, 'Times New Roman', serif" with tight letter-spacing; numbers with ui-monospace (SF Mono / Consolas). Body: system sans? Mixing serif headline + mono numbers gives ledger feel. Body text in serif too maybe. Let's do: everything serif for text, mono for numerals. Layout: max-width ~960px centered. Header: small caps label "SALES LEDGER — DATA CLEANED REPORT", big headline one-liner. Then a rule. Then stats row (4 tiles, thin-bordered, no cards shading — bordered boxes with hairlines). Then two sections: pivot table (left, larger) and bar chart (right) in a grid; on narrow, stack. Then footnote of cleaning rules applied. Pivot table: HTML table, right-aligned mono numbers, borders: hairline rows, heavy top border for totals. Grand total cell highlighted. Negative values in red with parentheses? Ledger style: ($450.00). I'll show negatives as -$450.00 with red. Ledger parentheses: ($450.00) in red — nice touch. Bar chart: SVG generated by JS. Horizontal bars: region label above bar or left column. Include value labels. Add small caption. Maybe show each region's bar segmented: positive gross and refunds? Could be nice: stacked bar — gross positive portion in ink, refund magnitude in red hatch. That's a nice touch showing refunds. Data: Texas gross = 3552.60+450 = 4002.60? Gross positive Texas Q1: 1240+312.5+870.1+1580=4002.60; refunds -450. Net 3552.60. Ohio Q2 gross 935.25 net 715.25... wait Ohio net Q2 = 2715.25 (760.25+515+1660 = 2935.25 gross, -220 refund → 2715.25). Stack: net bar plus red segment showing refunds appended? Simpler: draw bar = net revenue; overlay a red notch segment at the start representing refund magnitude? Might confuse. Alternative: bar shows net, and next to label a small red marker "2 refunds / −$670". I'll keep bars as net revenue with a thin red tick line at the refund magnitude end? Simpler and honest: draw net bar; under region label, small red text "incl. refunds −$450.00". Good enough. Actually more interesting: draw gross positive bar (length = gross), and inside/overlaid at left a red segment of length = refund magnitude, so net visible? Confusing. Keep clean: net bars, red refund annotation. Also mark top region bar in accent color, others ink. Fine — "one clear idea": net revenue ledger with refunds surfaced. Chart axes: baseline vertical line, gridlines at 0, 5k, 10k, 15k with mono labels. Horizontal bars with rounded? No, straight rects, height 40. Interactivity: hover on bars → tooltip? Add hover highlight on pivot cells with title attr. Add a bit: hovering a bar shows exact figure in a caption line. Also maybe a region hover on chart highlights matching pivot row — nice, cheap to implement. I'll do: hovering bar highlights the pivot row (class toggle). And pivot cells get tooltips via title element? HTML title attr works. Keep it. Also small "excluded rows" detail in data quality panel — show which ids were excluded on hover (title attr listing). Add footnote listing excluded order ids: 1006, 1017, 1028 and duplicate 1008. Nice for credibility. Let me structure: ``` <header> <div class=kicker>SALES LEDGER · FY2025 H1 · CLEANED EXPORT</div> <h1 id=headline>…</h1> </header> <section class=quality> 4 stat blocks </section> <main grid> <section pivot> <section chart> </main> <footer notes> ``` Compute everything in one script, render into DOM. Stat tiles: number big mono, label small caps. Border-left heavy? Use top border 2px ink and hairline elsewhere. Colors: paper #f6f3ec; ink #1c1a16; hairline #d8d2c4; accent red #b23b2b; highlight (top region) #2f5d3f? Hmm accent must be one strong idea. Use crimson #a8332a for negatives/excluded and top-region emphasis via ink weight + underline? Let me pick: accent = #b23b2b (ledger red) used for refunds, excluded stat, and the top-region bar? Top region highlighted in red might read as negative. Use deep green #35573f for the top bar and positive emphasis. Two accents might be too many. Palette: ink, paper, hairline, red for negatives only; top region bar gets ink at full strength plus a small "TOP" tag in red? I'll make top region bar colored #a8332a? No. Decision: single accent = ledger red #b23b2b used for: refund values, excluded count, and a thin underline under the top region's name in headline. Bars: top region filled ink-dark #1c1a16, others filled with 60% ink (#8b867c-ish?). Actually fill others #b9b2a3 (muted), top one ink. That gives clear hierarchy. Good. Number formatting: US locale, $ with commas, 2 decimals. Pivot totals: row total column "Total", bottom row "Total" and grand total. Bottom-left cell "Q1 + Q2 Total"? Standard: row header "Total". Let me compute chart scale: max = 16091.26. Chart width viewBox 520x? Bars horizontal: label column 90px, bars area ~380, values at end. Use SVG width 100% viewBox="0 0 520 200". Gridlines at 0/5000/10000/15000 → x positions map value→width. Implement in JS: build svg string. Bar geometry: three bars, y = 30 + i*52, height 34. Chart area x0=100 to x1=500 (400px for 16091 max → scale). Gridlines each 5000 up to 15000? max ~16091 → lines at 5k,10k,15k; also value labels. Refund annotation: small red text right after value? Under region label: e.g. "Texas" and beneath in 9px red "2 refunds · −$450.00". Wait Texas refunds: only 1009 (−450) → 1 refund. Ohio: 1023 (−220) → 1. California: 0 refunds. Refund totals: Texas −450, Ohio −220, CA $0.00. Total refunds 2, sum −670. Order counts per region for headline maybe: California 11 counted orders? Count: CA Q1: 1002,1004,1008,1012,1015 =5; Q2: 1018,1021,1025,1027 =4 → 9 orders. Texas: Q1 1001,1003,1009,1010,1013=5; Q2 1016,1019,1022,1024,1030=5 → 10. Ohio: Q1 1005,1007,1011,1014=4; Q2 1020,1023,1026,1029=4 → 8. Total counted 26 ✓. Headline: "California leads with $16,091.26 in net revenue." One line, computed. Pivot table cells: values as ledger style; negative in red parentheses. Row total column, total row, grand total bottom-right in bold with top double border. Also show order counts? Keep table clean, just dollars. Maybe include "(n orders)" small? No — clean. Titles on cells: title="Texas · Q1 — 5 orders". Good micro-detail. Data quality: four tiles: Rows received 30; Duplicates dropped 1; Excluded (non-numeric) 3; Rows counted 26. Small red text under excluded: ids. Footer notes: rules applied, excluded ids list, dup id list. Write the code carefully. Ensure the CSV string uses backticks and contains no backticks. Contains quotes and commas — fine inside template literal. Now write the HTML. Script details: ```js const raw = `order_id,...`; const rows = parseCSV(raw); const header = rows[0]; // skip const data = rows.slice(1); ``` Cleaning: ```js const seen=new Set(); let dup=0, excluded=0, counted=0; const clean=[]; for(const r of data){ const id=r[0].trim(); if(seen.has(id)){dup++; dupIds.push(id); continue;} seen.add(id); const amt=parseAmount(r[4]); if(amt===null){excluded++; excl.push(id); continue;} counted++; clean.push({id, date:r[1], region:normRegion(r[2]), amount:amt, quarter:quarterOf(r[1])}); } ``` Pivot build: ```js const regions=['California','Ohio','Texas']; // or sorted dynamic const quarters=['Q1','Q2']; ``` Build dynamically: collect set of quarters present, sorted. Regions: sorted alphabetically. Compute cell sums and order counts. Rendering pivot: build HTML string. Bar chart: build svg. Also refund info per region for chart annotation. Let me write the final file now. Formatting function: ```js const fmt=n=>{ const neg=n<0, a=Math.abs(n); const s=a.toLocaleString('en-US',{minimumFractionDigits:2,maximumFractionDigits:2}); return neg? `($${s})` : `$${s}`; }; ``` Negative style in pivot: class neg → red. Headline: `$${top.toLocaleString(...)}` without parens since positive. Bar chart SVG code: ```js function chartSVG(){ const W=560,H=210,pad={l:96,r:16,t:18,b:34}; const chartW=W-pad.l-pad.r; const max=Math.max(...regions.map(r=>cell total)) * 1.08; const scale=chartW/max; const barH=30, gap=18; const y0=pad.t; // gridlines let g=''; const steps=4; // nice steps: use max rounded to nice: ceil to nearest 5000 const nice=Math.ceil(max/5000)*5000; ... } ``` I'll compute nice max = ceil(max/5000)*5000 = 20000 for 16091*1.0. Use maxData=16091.26, nice=20000 → ticks at 5000,10000,15000,20000? 20000 makes bars look shortish; use step 5000, ticks 5k..15k plus end 20000? Actually with nice=20000 and 4 gridlines (5,10,15,20k) fine. Bar y positions: bar i: y = pad.t + i*(barH+gap). H = pad.t + 3*(30+18) - gap + pad.b ≈ 18+144+34=196 → H=200. Region label above bar: text at x=pad.l-8, text-anchor=end, y = barY + barH/2 + 4? Put region name at left aligned baseline middle. And refund annotation inside bar? Place refund note to the right of value? Simpler: value at end of bar (outside, right), refund note small under region name in left column — left column width 96 might be tight for "California" at 13px (approx 66px) plus refund note "1 refund · −$450.00" ~ 100px at 8.5px mono → too wide. Alternative: refund note inside the chart area under the bar: small red text at x=pad.l, y=barY+barH+11: "incl. refund −$450.00". With gap 18 that collides with next bar (barH 30 + note at +11 → within 18 gap? bar bottom at y+30, note at y+41, next bar top at y+48 → ok tight). Increase gap to 24, barH 32 → row 56. H = 18 + 3*56 - 24 + 34 = 204 → 210. Value label: at x = pad.l + barWidth + 8, mono 12px, anchored start. For top bar bold. Hover interplay: bars get data-region attr; on mouseenter add .hl to matching pivot row. Also change fill on hover slightly. Use CSS for svg: rect:hover {fill:...} but top bar already ink; give hover fill via JS class toggling: bar rect class "bar", data-region; css .bar{fill:var(--muted)} .bar.top{fill:var(--ink)} .bar.hl or row highlight? Let's do: hovering a bar → tooltip text? Simplest robust: hovering bar updates a caption element below chart showing exact numbers ("California — 9 orders · $16,091.26 net · no refunds"). Nice. Implement mouseenter/mouseleave listeners (SVG rects support events). Also pivot row hover highlights bar: add class to rect. Let me write everything. CSS: ```css :root{--paper:#f6f3ec;--ink:#1c1a16;--mut:#8b857a;--hair:#dcd6c8;--red:#b23b2b;} *{box-sizing:border-box;margin:0;padding:0} body{background:var(--paper);color:var(--ink);font-family:Georgia,'Times New Roman',serif;padding:48px 24px 64px;} .wrap{max-width:980px;margin:0 auto} .kicker{font:11px/1 ui-monospace...;letter-spacing:.24em;...} ``` Use mono font stack: `ui-monospace, 'SFMono-Regular', Menlo, Consolas, monospace` — define --mono. Headline: serif, 34px, letter-spacing slight negative, with the region name underlined in red? I'll bold region and its total in mono? Mixing mono inside serif headline: `<em class=mono>`? Could look nice: "California leads H1 with $16,091.26 in net revenue." Put the dollar figure in mono, slightly smaller, baseline aligned. Keep simple: entire headline serif, numbers will render in serif — acceptable but ledger mono is nicer. I'll wrap figure in span with mono font, size 0.82em, red underline? Actually keep red accent: figure in red? Red = negative connotation. Use ink, but give the top region name a red underline (border-bottom). Hmm — I said red for refunds/excluded. Underline in red is emphasis, ok, sparingly. Actually let me restrain: red only for negative amounts, the "excluded" stat number, and refund annotations. Top region emphasis via full-ink bar and bold. Headline plain but strong. Table CSS: width 100%, border-collapse: collapse; cells padding 10px 14px; mono numbers right aligned; hairline row borders; header small caps letter-spaced; totals row top border 2px ink; grand total bold; numeric cells title attrs. Section titles: "Revenue by region × quarter" and "Net revenue by region" — small caps kickers with rule. Grid: `.duo{display:grid;grid-template-columns:1.25fr 1fr;gap:40px}` media stack. Quality tiles: grid 4 cols; each tile: border-top 3px solid ink (excluded tile red border-top), big mono number 28px, label small caps. Duplicate note under. Footnotes: hairline top rule, small mono text lines: cleaning rules applied, excluded ids, dup id. Now the script. Careful with quarter detection for "Jan 21, 2025": regex `^([A-Za-z]+)\s+\d` matches "Jan". Use map of full names to month: jan→1 etc. "Mar 12" → 3 → Q1. "Jun 17" → 6 → Q2. Also "texas " trailing space in region — trim handles. Amount "-450.00" → cleaned "-450.00" matches regex ^-?\d*\.?\d+$ → ok ("450.00" after optional '-' → "-450.00": pattern ^-?\d*\.?\d+$: '-' then \d* matches '450', then \.? then \d+ '00' → yes). "1999.99" ok. "870.10" ok. "$760.25" strip $ → 760.25 ok. "1,240.00" strip commas ok. "$980" ok. "N/A" → cleaned "N/A" fails regex → null. "unknown" → null. Good. Edge: amount like "-220.00" ok. Quarter of "2/3/2025" → month 2 → Q1 ✓. "6/30/2025" month 6 Q2 ✓. Now compute in JS everything dynamically; no hardcoding results. Headline: top region by net total; text: `${topRegion} leads the half with ${fmtPlain(topTotal)} in net revenue.` fmtPlain = "$16,091.26" (no parens needed). One line ✓. Chart caption default: "Hover a bar for detail." Let me write chart code concretely: ```js const bars = regions.map(r=>({region:r, net:regTotal[r], orders:regOrders[r], refunds:regRefunds[r] /* sum magnitude */, refundCount})); ``` Build SVG with string. width fixed 560 viewBox, responsive via width:100%. Ticks: nice = Math.ceil(max/5000)*5000 → 20000. Ticks at 0,5000,10000,15000,20000? Draw hairlines from y0 to bottom at each tick >0, label under axis at bottom (pad.b area): tick labels at y=H-12. Baseline vertical line at x=pad.l from pad.t to H-pad.b+? Draw axis line. Scale: sc = chartW/nice. Bar: x=pad.l, width=net*sc. Value label: fmt without parens e.g. "$16,091.26" at end. If label would overflow (bar near max), still fine since max bar 16091 < nice 20000, label has room. Refund note: if refundCount>0: red text at x=pad.l+2, y = barY+barH+12? Place under bar start: text 9px mono fill red: `${refundCount} refund${s} · −$450.00`. Use minus sign char "−". Compute refund sum magnitude from amounts<0: abs sum. Row spacing: rowH = barH+gap where gap includes note space: barH=30, rowGap=26 → rowH=56. y_i = pad.t + i*rowH + maybe center within? Fine. H = pad.t + 3*56 - 26 + 38 = 18+168-26+38=198 → round 200. pad.b=38 gives tick labels at H-16. Gridlines: for t in [5000,10000,15000,20000]: x=pad.l+t*sc... wait scale uses nice=20000, chartW=560-96-16=448; sc=448/20000=0.0224. Bar for 16091 → 360px, label at +8 → 96+360+8=464, text ~70px → 534 < 560 ok. Tick label format: "$5,000" or "5k"? Use "$5K"? mono small: "$5,000" fits. Use tick labels "$5k","$10k","$15k","$20k". Good. Top region bar: others fill #b8b1a2 (muted). Hover: fill darkens via CSS: .bar:hover{fill:var(--ink)} but top already ink — fine, top hover maybe red? Keep uniform: hover → ink. Interaction: attach listeners after injecting via DOM (need real elements). I'll build svg string then set innerHTML on container, then query .bar rects and bind events updating #chartCap text: e.g. `California — 9 orders · net $16,091.26 · no refunds` or `1 refund (−$450.00) netted`. Also hovering bar adds 'hl' to pivot row: rows have data-region; row hl style background hairline-ish (#ece7da). Pivot build: ```js let html = `<table>...`; ``` Header cells: blank, Q1 (Jan–Mar), Q2 (Apr–Jun), Total. Cell title: `${region} · ${q} — ${n} orders, net ${fmtplain(v)}`. Row: region name cell (serif, left) + numbers. Total row: "All regions" + col totals + grand bold. Also add small "n=" counts? Keep clean. Numbers with class neg when <0 (red). Row totals column separated with left border 2px? Use border-left: 2px solid ink on total column cells? A heavier hairline (#b9b2a3). Bottom row top border 2px ink; grand total bold. Alright, write it. Also ensure "rows received" counts data rows excluding header (30). Header not counted. Refund handling note: "Negative amounts treated as refunds and netted against revenue" in footnotes. Excluded note lists: 1006 (N/A), 1017 (unknown), 1028 (N/A). We can reconstruct reason: store the raw amount string when excluded. Dup note: 1008 kept first of 2 occurrences. Write final code. Also make sure the excluded tile border-top red and number red. Let me now write the full file, mindful of length but complete. One more check on chart label widths: left column 96px for "California" at 13px serif — approx 62px fine. Chart section header: "NET REVENUE BY REGION" kicker. Add legend? Red note explains refunds; the in-chart notes suffice. Add tiny footnote in chart: "Refund amounts are netted out of the bars." small. Now finalize JS numbers formatting for plain (no parens): fmtP = n => '$'+abs formatted with maybe minus: for refunds annotation: `−$450.00` manually: `'−$'+a.toLocaleString(...)`. Implementation of refund annotation text: refunds count and total magnitude: e.g. Texas: "1 refund · −$450.00". Ohio: "1 refund · −$220.00". California: none → no note (or "no refunds"). Leave blank for none to reduce noise? Put nothing. Also pivot grand total check equals 34083.00 — computed in code, fine. Write code now. Also body max width; responsive: table maybe overflow-x on small screens: wrap table in .tbl{overflow-x:auto}. Headline element id="headline". Let me draft the full HTML mentally and output. Edge: parseCSV: header row filter r.length>1 ok; also trailing newline yields empty last row filtered. For excluded rows, keep rawAmount for footnote: excl.push({id, raw:r[4].trim()}). Chart caption element below svg: id="chartCap". Order of script: define helpers, raw csv, parse, clean, compute, render headline, quality, pivot, chart. Quality tiles markup: ```html <div class="tiles"> <div class="tile"><div class="num">30</div><div class="lbl">Rows received</div></div> <div class="tile"><div class="num">1</div><div class="lbl">Duplicates dropped</div></div> <div class="tile excl"><div class="num">3</div><div class="lbl">Rows excluded</div></div> <div class="tile"><div class="num">26</div><div class="lbl">Rows counted</div></div> </div> ``` Fill via JS with actual counts. Tiles: grid 4; tile border-top 3px ink; excl border-top red, num red. num font mono 30px. lbl 10px caps letter-spaced mut. Section headers styling: kicker row with hairline: `.sec{margin-top:44px} .sechd{display:flex;align-items:baseline;justify-content:space-between;border-bottom:2px solid var(--ink);padding-bottom:8px}` with kicker left and small note right. Pivot note right: "Q1 = Jan–Mar · Q2 = Apr–Jun". Chart note: "refunds netted". Duo grid below quality: gap 48, but table wide — maybe stack vertically instead: pivot full width, then chart? The chart is horizontal bars, could sit beside table. Table has 5 columns; fine side by side at 980 width: table ~460px, chart 560 scaled. Use grid-template-columns: 1fr 1fr with chart svg width 100%. OK. Footer notes list rules: - order_id deduped — first occurrence kept (dropped: 1008 ×1) - non-numeric amounts excluded: 1006 "N/A" · 1017 "unknown" · 1028 "N/A" - negative amounts = refunds, netted as negative revenue (2 refunds, −$670.00) - regions normalized: TX/tx/Texas/texas → Texas · CA/california → California · OH/ohio → Ohio - dates parsed from ISO, M/D/YYYY, "Mon D, YYYY" → quarters derived Render these as small mono lines. Include dynamic ids. Grand total also displayed? Headline covers top region. Fine. Write it all out now. Also ensure no emoji, no alerts. Fonts: Georgia is fine as identity? Georgia is common but as serif ledger it reads intentional; paired with mono numerals it's cohesive. Good enough given no external resources. Minus sign: use "−" (U+2012/2212). In JS string fine. Let me write the code. ```html <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width,initial-scale=1"> <title>Sales Ledger — Cleaned Export
