Quality Evaluation
Evaluator Score Verdict Claude 90/100 approve Criteria Checklist
Visual Quality:
- VQ-001: Axes labeled correctly - "Time" (x) and "Value" (y) are meaningful labels
- VQ-002: Visual clarity - Grid is subtle with alpha=0.3 and dashed style
- VQ-003: Elements clear - Line with width 2.5 and markers clearly visible
- VQ-004: No overlap - Labels, ticks, title are all readable without overlap
- VQ-005: Legend present - N/A (single series, legend not required)
- VQ-006: Colorblind safe - Uses "steelblue" which is accessible
- VQ-007: Image size - Default is 1600×900 instead of 4800×2700 target (partial)
- VQ-008: Title present - "Basic Line Plot" is centered and clear
Code Quality:
- CQ-001: Type hints present - All parameters have proper type annotations
- CQ-002: Docstring complete - Google-style with Args, Returns, Raises, Example
- CQ-003: Input validation - Empty data, column existence, numeric type checks
- CQ-004: Clear error messages - Includes available columns in KeyError
- CQ-005: No magic numbers - All values are parameters with defaults
Correctness:
- CR-001: Data accurate - Correct column usage, proper x/y mapping
- CR-002: Spec compliance - Implements time series/sequential line visualization per spec
- CR-003: Edge cases - NaN handling via dropna(), empty data raises ValueError
Issues Found
- VQ-007 PARTIAL: Default dimensions are 1600×900 instead of recommended 4800×2700. However, these are configurable parameters and the rendered test plot works correctly.
Positive Observations
- Excellent use of ColumnDataSource per bokeh best practices
- Smart x-axis type detection (datetime vs auto)
- Data sorting ensures proper line connection
- Configurable markers for data point visibility
- Toolbar with useful interactions (pan, zoom, reset, save)
- Subtle grid styling with dashed lines
AI Feedback for Next Attempt
No critical issues. Consider updating default width/height to 4800/2700 in future iterations.
