Criteria Checklist

Visual Quality

VQ-001: Axes labeled correctly - Y-axis has "Value" label, X-axis shows categories
VQ-002: Visual Clarity - Grid is subtle with dotted style, doesn't dominate data
VQ-003: Elements Clear - Box plots clearly visible with appropriate colors and contrast
VQ-004: No Overlap - Labels, ticks are well-spaced, no overlapping text
VQ-005: Legend Present - N/A (single series type, legend appropriately disabled)
VQ-006: Colorblind Safe - Uses distinct colors (teal, yellow, blue, pink) that are distinguishable
VQ-007: Image Size - Default 1600x900, not 4800x2700 target (minor, parameterized)
VQ-008: Title - "Basic Box Plot" centered and clear

Code Quality

CQ-001: Type hints present on all function parameters and return type
CQ-002: Docstring complete with Args, Returns, Raises, Example
CQ-003: Input validation present (empty data, missing columns)
CQ-004: Clear error messages with available columns listed
CQ-005: No critical magic numbers - sizes are parameterized with defaults

Correctness

CR-001: Data Accurate - Correctly calculates Q1, median, Q3, IQR, whiskers, and outliers
CR-002: Spec Compliance - Implements all required features: multiple groups, quartiles, whiskers at 1.5×IQR, outliers as individual points
CR-003: Edge Cases - Handles empty data, missing columns, NaN values (via dropna)

Issues Found

VQ-007 PARTIAL: Default image dimensions are 1600x900 instead of target 4800x2700. However, width/height are parameterized so users can override.

Strengths

Proper box plot statistics calculation (Q1, median, Q3, IQR, whiskers)
Outlier detection and display as separate scatter series
Color-coded boxes for each group
Clean tooltip formatting showing all statistics
Follows Highcharts library guidelines (container="container", inline scripts, highcharts-more.js for boxplot)
Comprehensive input validation with helpful error messages

AI Feedback for Next Attempt

If regeneration needed: Update default width/height to 4800/2700 to match style guide target dimensions.

Verdict: APPROVED

The implementation correctly creates a box-and-whisker plot comparing statistical distributions across 4 groups. Each box properly displays quartiles (Q1, median, Q3), whiskers extend to 1.5×IQR range, and outliers appear as individual red points. The code is well-structured with proper type hints, validation, and documentation. The only minor issue is the default image size, but this is parameterized and doesn't affect functionality.
