Quality Evaluation
Evaluator Score Verdict Claude 92/100 approve Criteria Checklist
- VQ-001: Axes labeled correctly (N/A for pie charts - no axes)
- VQ-002: Visual clarity - clean white background, clear slices
- VQ-003: Elements clear - slices well-sized with white borders, percentages readable
- VQ-004: No overlap - labels, legend, and title don't overlap
- VQ-005: Legend present - displayed on right side with all categories
- VQ-006: Colorblind safe - uses PyPlots palette (blue, yellow, red, green, violet)
- VQ-007: Image size - 1600x900 with scale=2 (3200x1800 output)
- VQ-008: Title - centered and clear "Basic Pie Chart"
- CQ-001: Type hints present - all parameters and return type annotated
- CQ-002: Docstring - complete Google-style with Args, Returns, Raises, Example
- CQ-003: Input validation - checks empty data, missing columns, negative values, zero sum
- CQ-004: Clear error messages - includes available columns in KeyError
- CQ-005: No magic numbers - figsize, colors, etc. are parameters with defaults
- CR-001: Data accurate - correct columns used, proportions match spec
- CR-002: Spec compliance - all required features implemented (categories, values, percentages)
- CR-003: Edge cases - handles empty data, negative values, zero sum
Issues Found
- VQ-007 MINOR: Image saved at 3200x1800 (scale=2) instead of target 4800x2700 (scale=3 per plotly.md guidelines)

The implementation is excellent overall. One minor improvement: change
scale=2toscale=3in thewrite_image()call to meet the 4800x2700 target resolution per plotly library guidelines.Verdict: APPROVED
The implementation correctly creates a basic pie chart matching the spec requirements. It displays proportional slices with percentage labels, uses a colorblind-safe palette, includes a legend, and has comprehensive input validation with clear error messages. The code follows plotly best practices and includes proper type hints and documentation.
