Issues Found

1. VQ-007 PARTIAL: Image dimensions are 1600x900 instead of the recommended 4800x2700 px per style guide. The code has width/height defaults of 1600/900 instead of 4800/2700.

Positive Highlights

• Excellent code quality with comprehensive type hints and docstrings
• Robust input validation covering multiple edge cases
• Clean visual output with proper legend placement
• Follows highcharts library-specific rules (container="container", inline JS for headless Chrome)
• Uses PyPlots style guide colors correctly
• Data labels show both category names and percentages

AI Feedback for Next Attempt

Update default width/height parameters from 1600/900 to 4800/2700 to match style guide requirements.
Also update the HTML container div style and Chrome window-size argument in the __main__ block.

Verdict: APPROVED

The implementation is high quality with proper code structure, validation, and visual output. The image size deviation is minor and doesn't significantly impact the overall quality. Score of 88 meets the ≥85 threshold.
