    Quality Evaluation

    Evaluator	Score	Verdict
    Claude	95/100	approve

    Criteria Checklist

    • VQ-001: Axes labeled correctly ("Month", "Sales")
    • VQ-002: Grid is subtle (dashed, alpha=0.3)
    • VQ-003: Elements clear (area fill visible, line distinguishable)
    • VQ-004: No overlap (labels and ticks readable)
    • VQ-005: Legend present (N/A - single series)
    • VQ-006: Colorblind safe (steelblue)
    • VQ-007: Image size correct (16:9 at 300 dpi)
    • VQ-008: Title present and centered
    • CQ-001: Type hints present on all parameters
    • CQ-002: Google-style docstring with Args, Returns, Raises, Example
    • CQ-003: Input validation for empty data and missing columns
    • CQ-004: Clear error messages with available columns listed
    • CQ-005: No magic numbers (uses parameterized defaults)
    • CR-001: Data accurate (correct X/Y mapping)
    • CR-002: Spec compliance (filled area chart as specified)
    • CR-003: Edge cases handled (empty data, missing columns)

    Issues Found

    None. Implementation is excellent.

    Notes

    • Good approach using matplotlib's fill_between with seaborn styling since seaborn doesn't have a native area chart function
    • Clean code structure with proper separation of line and fill
    • Y-axis starts from 0 as is standard practice for area charts
    • Uses seaborn's set_theme(style="whitegrid") for consistent appearance

    Verdict: APPROVED
