    Criteria Checklist

    • VQ-001: Axes labeled correctly ("Value" and "Frequency" are meaningful)
    • VQ-002: Visual clarity - grid is subtle (only Y guides, light gray)
    • VQ-003: Elements clear - bars visible with good opacity (0.8)
    • VQ-004: No overlap - labels and title properly positioned
    • VQ-005: Legend - correctly hidden for single series
    • VQ-006: Colorblind safe - uses Python Blue (#306998)
    • VQ-007: Image size - correct 4800 × 2700 px
    • VQ-008: Title - "Basic Histogram" centered and clear
    • CQ-001: N/A - Plot implementations use KISS style per project guidelines
    • CQ-002: N/A - Plot implementations use KISS style per project guidelines
    • CQ-003: N/A - Script-style implementation as required
    • CQ-004: N/A - Script-style implementation
    • CQ-005: N/A - Script-style implementation
    • CR-001: Data accurate - correctly uses normal distribution with mean=100, std=15
    • CR-002: Spec compliance - all requirements met (distribution, bins, labels)
    • CR-003: N/A - Script-style, uses fixed seed for reproducibility

    Issues Found

    None - implementation is clean and follows all requirements.

    Strengths

    1. Correct use of pygal.Histogram() chart type with proper data format (height, start, end)
    2. Clean KISS-style implementation (no functions/classes) as per project guidelines
    3. Custom style properly configured with appropriate colors and font sizes
    4. Histogram bins calculated correctly using numpy
    5. Fixed random seed (42) for reproducibility

    AI Feedback for Next Attempt

    No issues found. Implementation is ready for merge.

    Verdict: APPROVED
