Quality Evaluation
Evaluator Score Verdict Claude 88/100 approve Criteria Checklist
Visual Quality:
- VQ-001: N/A (Pie charts don't have X/Y axes - axes correctly hidden)
- VQ-002: Visual Clarity - Grid disabled (appropriate for pie), clean design
- VQ-003: Elements Clear - All pie slices clearly visible with good contrast
- VQ-004: No Overlap - Labels well positioned, no overlap with legend or other elements
- VQ-005: Legend Present - Legend properly displayed on right side with all categories
- VQ-006: Colorblind Safe - Uses distinguishable colors (blue, yellow, red, green, violet)
- VQ-007: Image Size - Uses 1600x900 instead of target 4800x2700 (partial compliance)
- VQ-008: Title - "Market Share Distribution" centered and clear
Code Quality:
- CQ-001: Type hints present for all function parameters and return type
- CQ-002: Comprehensive Google-style docstring with Args, Returns, Raises, Example
- CQ-003: Input validation for empty data, missing columns, non-numeric, negative values, zero sum
- CQ-004: Clear error messages with available columns listed
- CQ-005: Configuration parameters exposed (startangle, colors, legend_loc, etc.)
Correctness:
- CR-001: Data Accurate - Correct data columns used, values match spec
- CR-002: Spec Compliance - All spec requirements met (5 categories, correct values, proportions displayed)
- CR-003: Edge Cases - Proper handling with ValueError/KeyError raises
Issues Found
- VQ-007 PARTIAL (-4): Figure dimensions are 1600x900 instead of target 4800x2700. However, the 16:9 aspect ratio is maintained.
- Minor Visual: Legend entries show category names but color indicator boxes appear as small black squares rather than matching the pie slice colors. This is a known Bokeh rendering quirk with LegendItem index references.

N/A - Implementation passes quality threshold
Verdict: APPROVED
The bokeh implementation is well-crafted. Since Bokeh lacks a native pie chart method, the use of wedge glyphs is the correct approach. The code includes comprehensive type hints, thorough input validation, and a detailed docstring. The visual output clearly shows proportions with percentage labels and a functional legend. Score of 88/100 exceeds the 85 threshold.
