Light render (`plot-light.png`): The chart renders on a warm off-white #FAF8F1 background. The title "sunburst-basic · pygal · anyplot.ai" is displayed in dark ink at the top and is clearly legible. The chart body occupies nearly the full square canvas. Four colored rectangular blocks are visible: a large orange/vermillion block (Business, Okabe-Ito #D55E00) at the top-left, a large teal/green block (Technology, #009E73) at the bottom spanning most of the width, a pink/purple block (Marketing, #CC79A7) at the top-right split into two sections, and a muted blue block (Operations, #0072B2) at the lower-right. Faint internal dividers subdivide each major block into sub-segments, but no text labels appear inside the rectangles. The legend at the bottom lists Technology, Business, Operations, and Marketing with colored indicators. All visible text is readable against the light background.
Dark render (`plot-dark.png`): The same layout renders on a warm near-black #1A1A17 background. Title and legend text appear in a light cream tone and are fully legible — no dark-on-dark failures. The data colors are perceptually similar to the light render (same Okabe-Ito hex codes in code), though the orange appears more red-brown against the dark surface — this is a perception contrast effect, not a code-level color change. Both renders use the correct background tokens and no chrome elements are theme-broken.
CRITICAL NOTE: Both renders show a treemap (nested rectangles), not a sunburst chart (concentric rings). This is a wrong-chart-type failure.

Visual Quality (27/30)
VQ-01: Text Legibility (7/8) — Sizes explicitly set (title_font_size=72, etc.). All visible text readable in both themes. Minor deduction: sub-segment labels invisible inside rectangles in static PNG.
VQ-02: No Overlap (6/6) — No overlapping text elements visible.
VQ-03: Element Visibility (5/6) — Rectangles are clearly visible. Internal subdivision lines within parent blocks are very faint and barely distinguishable; no sub-segment labels are shown.
VQ-04: Color Accessibility (2/2) — Okabe-Ito palette is CVD-safe. Good contrast between segments.
VQ-05: Layout & Canvas (4/4) — 3600×3600 square canvas. Chart fills the canvas well; title and legend are properly positioned.
VQ-06: Axis Labels & Title (1/2) — Title uses correct format. No axis labels needed for this chart type; score reflects title-only.
VQ-07: Palette Compliance (2/2) — First series (Technology) correctly uses #009E73. Subsequent series follow Okabe-Ito order. Backgrounds are #FAF8F1 / #1A1A17 in both renders. Chrome flips correctly between themes.
Design Excellence (8/20)
DE-01: Aesthetic Sophistication (4/8) — Looks like a well-configured library default. Theme tokens and palette are properly wired; no further design thought applied.
DE-02: Visual Refinement (2/6) — Minimal customization beyond applying the Style object. No refinement specific to treemap/sunburst layout.
DE-03: Data Storytelling (2/6) — Data is displayed proportionally but there is no visual hierarchy, emphasis, or focal point guiding the viewer's eye.
Spec Compliance (6/15)
SC-01: Plot Type (0/5) — WRONG CHART TYPE. The spec requires a sunburst chart (concentric rings showing hierarchy). The implementation uses pygal.Treemap() which renders nested rectangles — an entirely different chart type.
SC-02: Required Features (1/4) — 2-level hierarchy (departments → teams) is represented and proportional sizing is correct. Missing: concentric ring structure, visible segment labels on chart, 3rd-level hierarchy option.
SC-03: Data Mapping (2/3) — Hierarchical data is mapped proportionally. Values drive rectangle area correctly. Deduction for wrong visualization paradigm.
SC-04: Title & Legend (3/3) — Title format sunburst-basic · pygal · anyplot.ai is correct. Legend lists all 4 departments.
Data Quality (13/15)
DQ-01: Feature Coverage (4/6) — 2-level hierarchy with varied values (40–180 $K) is good coverage. Missing optional 3rd hierarchy level.
DQ-02: Realistic Context (5/5) — Organizational budget breakdown by department/team is realistic and editorially neutral.
DQ-03: Appropriate Scale (4/4) — Team budget values in the 40–180 $K range are sensible for this domain.

Score Caps Applied
SC-01 = 0 (wrong plot type) → max score capped at 40. Raw score 69 → capped to 40.
Strengths
Correct Okabe-Ito palette with #009E73 as first series (Technology)
Theme-adaptive chrome: backgrounds, text, and legend all flip correctly between light/dark
Correct title format and HTML+PNG output
Clean code structure with explicit font sizes
Realistic, neutral organizational budget dataset
Weaknesses
CRITICAL: Uses pygal.Treemap() instead of a sunburst (concentric rings). A treemap shows hierarchical rectangles; a sunburst shows hierarchical concentric arcs/rings. These are fundamentally different chart types.
Sub-segment labels (Backend Engineering, Sales, etc.) are not rendered inside blocks in static PNG output — the sub-divisions within each block are only faintly suggested by thin lines.
Only 2 hierarchy levels; the spec supports 2–4 and a 3rd level would better demonstrate the feature.
Issues Found
SC-01 CRITICAL: pygal.Treemap() is used — this renders rectangular blocks, not concentric rings.
Fix: Replace with pygal.Pie() with multiple chart.add() calls where each call represents one ring. The first add() becomes the inner ring (departments with their total values), and the second add() becomes the outer ring (teams, listed in department order so angular alignment is preserved).
SC-02: Sub-segment labels missing from static render; hierarchy depth is shallow.
Fix: Ensure team-level labels are included as {'value': X, 'label': '...'} dicts in the outer-ring series.
AI Feedback for Next Attempt
Replace pygal.Treemap() with pygal.Pie() to produce concentric rings (sunburst). Use two chart.add() calls: the first adds the 4 departments as a flat list of {'value': total, 'label': dept} dicts (inner ring), and the second adds all 10 teams in department order as {'value': v, 'label': team} dicts (outer ring). Consider inner_radius=0.2 on the Pie for a donut-like center hole that distinguishes the hierarchy levels. Keep all theme tokens, palette, and output format unchanged — those are correct.
Light render (plot-light.png): The plot shows a square (3600×3600 px) treemap on a warm off-white #FAF8F1 background. Four colored rectangles represent the four departments: the large bottom area is green (#009E73, Technology), the large top-left area is vermillion-orange (#D55E00, Business), the upper-right area is pink/reddish-purple (#CC79A7, Operations or Marketing), and a blue-steel (#0072B2) section. The title "sunburst-basic · pygal · anyplot.ai" is rendered in dark text at the top — clearly readable. The legend at the bottom shows four colored dots with department labels (Technology, Business, Operations, Marketing) — readable. There are no segment labels inside the rectangles. All text is readable against the light background. Legibility: PASS.
Dark render (plot-dark.png): The same treemap appears on a near-black #1A1A17 background. The data colors are visually identical to the light render — green, burnt-orange, muted pink, and dark blue sections — the data palette does not change between themes, only the surface does. The title text is light-colored and clearly readable. The legend text at the bottom is light and legible. No dark-on-dark failures were found. Legibility: PASS. However, the fundamental issue — this is a Treemap, not a Sunburst — is present in both renders.

DE-03: Data Storytelling (2/6) — Data is displayed but the rectangular layout conveys no narrative or hierarchy emphasis; no visual hierarchy guides the viewer
Spec Compliance (6/15)
SC-01: Plot Type (0/5) — WRONG CHART TYPE.pygal.Treemap() was used instead of a sunburst chart. The spec requires concentric rings where each ring represents a hierarchy level (innermost = departments, outer rings = teams). A treemap uses rectangles; it does NOT show hierarchy via concentric rings.
SC-02: Required Features (2/4) — Hierarchical data (departments + teams) is present, but the concentric ring structure, ring-level visual separation, and the radial layout are all absent
SC-03: Data Mapping (2/3) — Values are proportionally mapped to areas; hierarchy is structurally present in the data, though not visible as rings

Strengths
Correct Okabe-Ito palette with #009E73 as the first series color
Both light and dark themes correctly implemented with proper background and chrome tokens
Clean, deterministic, KISS-structure code
Realistic organizational budget data with plausible values
Correct title format and output file naming
Weaknesses
Wrong chart type: pygal.Treemap is used instead of a sunburst chart — the entire chart type must change
No internal cell/segment labels on the treemap rectangles
Missing concentric ring hierarchy structure (the core requirement of sunburst-basic)
Font sizes slightly deviate from the pygal guide recommendation (title=72 vs recommended 28px)
Issues Found
SC-01 CRITICAL: pygal.Treemap() used instead of a sunburst chart. The spec requires concentric rings where each ring = one hierarchy level.
Fix: Use pygal.Sunburst() if available in pygal 3.1.0, and restructure data as parent-child hierarchy. If pygal.Sunburst is not available natively, use a pygal.Pie with multi-level data or a nested approach to approximate concentric rings.
DE-02 LOW: No internal labels inside the segments; hierarchy not visible from the chart itself without the legend.
Fix: In a sunburst chart, ensure each ring segment has a label, and inner ring segments visually encompass their children's angular spans.
AI Feedback for Next Attempt
The implementation MUST use a sunburst chart type, not a treemap. Check whether pygal.Sunburst exists in pygal 3.1.0 — if it does, use it with nested parent-child data structure. If pygal does not have a native Sunburst, use pygal.Pie in a multi-ring layout or Donut approach to simulate concentric rings. The data structure must reflect 2–3 levels of hierarchy (e.g., root → departments → teams), with inner segments spanning their children's angular range. Keep the correct Okabe-Ito palette, theme tokens, title format, and KISS code structure from this attempt.
Light render (plot-light.png): The chart renders on a warm off-white #FAF8F1 background — correct. The plot is a large circle divided into four colored sectors in Okabe-Ito order: green (#009E73, Technology ~42%), orange (#D55E00, Business ~36%), blue (#0072B2, Operations ~20%), and pink (#CC79A7, Marketing ~12%). Very faint arc lines near the outer perimeter suggest subcategory divisions, but they are barely discernible. There are no segment labels inside the chart body. The title "sunburst-basic · pygal · anyplot.ai" appears at the top in dark ink — readable. A bottom legend in small text identifies the four departments. All chrome text is readable against the light background. However, this is NOT a sunburst chart — it renders as a flat pie-like circle without concentric rings.
Dark render (plot-dark.png): Background is a near-black #1A1A17 — correct. Data colors are identical to the light render (green, orange, blue, pink in same Okabe-Ito order). The title and legend text appear in light-colored ink against the dark background — readable, with no dark-on-dark failures. No chrome inversion issues detected. The same flat pie appearance persists: no concentric rings, no visible hierarchy levels. The orange segment appears slightly more muted on the dark surface but remains distinguishable.
Both paragraphs are required. A review that only describes one render is invalid.

Strengths
Correct Okabe-Ito palette in canonical order with proper theme-adaptive backgrounds for both light and dark renders
Clean KISS code structure with properly set font sizes and correct output files (PNG + HTML)
Realistic and neutral organizational budget data with sensible proportions
Weaknesses
WRONG CHART TYPE: Uses pygal.Treemap instead of a sunburst chart — the rendered output is a flat pie-like visualization with barely visible subdivision lines, NOT concentric rings showing hierarchy levels. Must implement a two-level sunburst using pygal.Pie with nested/inner slices, or build concentric rings manually.
No segment labels inside the chart — only a tiny bottom legend identifies the 4 departments; subcategory labels (Backend Engineering, Frontend Engineering, etc.) are completely invisible in the render.
Hierarchy is not visually communicated — the inner ring (parent) vs. outer ring (child) structure required by the spec is absent.
Issues Found
SC-01 CRITICAL: pygal.Treemap used instead of a sunburst chart type
Fix: Use pygal.Pie with inner radius set to create a donut/sunburst effect, and add a second (inner) pie layer for the parent categories — OR use pygal.Pie with inner_radius plus separate chart.add() calls where parent data forms the inner ring. Consider using pygal.Pie with half_pie=False and creating two overlaid slices for each level.
DQ-01/SC-02: Subcategory level not rendered visually
Fix: When using the correct sunburst approach, ensure the outer ring explicitly shows the sub-team values (Backend Engineering, Frontend Engineering, etc.) with the inner ring aggregating to department totals.
DE-03 LOW: No visual hierarchy or data storytelling
Fix: Add segment labels or value annotations for major segments; use color variation within each branch to connect parent and children visually.
AI Feedback for Next Attempt
The fundamental issue is using pygal.Treemap instead of a sunburst. Pygal does not have a native Sunburst chart class, so the correct approach is to build a two-ring sunburst using pygal.Pie: create an outer pygal.Pie for the leaf nodes (subcategories) and an inner pygal.Pie with a large inner_radius (or use a second chart overlaid) for the parent departments. Alternatively, render two pygal.Pie instances with different inner_radius values and width/height to simulate concentric rings. The outer ring should show subcategory segments; the inner ring should show department totals. Use consistent branch colors (lighter/darker shades of the Okabe-Ito color for each parent) on children segments. Add segment labels for major slices.
Light render (plot-light.png): The chart renders on a warm off-white (#FAF8F1) background. Two concentric rings form a donut-style sunburst: the inner ring shows four large department slices (Technology in #009E73 green, Business in #D55E00 orange-vermillion, Operations in #0072B2 blue, Marketing in #CC79A7 pink-purple), and the thin outer ring shows team-level shaded variants of the same parent hues. The title "sunburst-basic · pygal · anyplot.ai" appears at the top in dark text, clearly readable. No segment labels appear on the static PNG; the legend that was declared at the bottom is not visible — it appears to have been clipped or not rendered by cairosvg. All text that is present is readable against the light background.
Dark render (plot-dark.png): The same chart structure renders on a near-black (#1A1A17) background. The title appears in light text and is clearly legible. The data segment colors occupy the same positions and proportions as the light render — the Okabe-Ito hues are consistent between themes, with only the background and title chrome flipping. No dark-on-dark failures detected. The legend is again absent from the static PNG. Both renders are readable.

Score Caps Applied
None applied — no zero scores in cap-triggering categories
Strengths
Correct sunburst simulation using pygal's native multi-series Pie API
Color-shading hierarchy: team segments use tinted variants of their department color, clearly linking children to parents
Proper theme-adaptive chrome: backgrounds, foreground, and muted tones all correctly derived from ANYPLOT_THEME
Deterministic, clean, flat code with no unnecessary complexity
HTML interactive output provides hover labels that compensate for the static PNG limitation
Weaknesses
No segment labels visible in the static PNG render — major segments should be labeled (department names at minimum) even in static output
Legend at bottom is not rendered in the PNG export by cairosvg; either accept this (HTML has it) or remove show_legend to avoid a misleading absence
Only 2 hierarchy levels used; a 3rd tier would fill out the spec's stated range of 2-4 levels and improve feature coverage
Issues Found
SC-02 / VQ-01: No static labels on segments — the spec explicitly requires labeling major segments; test whether print_labels=True produces visible text in cairosvg output
SC-04: Legend declared but absent in PNG — if pygal's legend does not survive PNG rendering, remove the legend options to rely on the HTML for full interactivity
DE-03 LOW: No storytelling beyond structure — consider a subtitle noting the largest department or total budget
AI Feedback for Next Attempt
The core sunburst structure, theming, and code quality are solid. The primary gap is static labeling: segment names are invisible in the PNG render. Attempt to add visible labels via print_labels=True or by testing whether pygal renders the label dict key as SVG text in the cairosvg path. If labels remain invisible in PNG, add a concise subtitle or annotation identifying the departments. Also remove or suppress the legend declaration if it does not appear in the PNG. A third data tier (e.g., sub-projects under each team) would push DQ-01 to full marks.
