+quality_score: 91
+review:
+  strengths:
+  - Excellent creative solution using XY chart to achieve box plot with strip overlay
+    (pygal.Box does not support strip overlay natively)
+  - Well-designed color scheme with matching box and point colors for each category
+  - Good use of custom Style for proper font sizing at 4800x2700 resolution
+  - Clear statistical visualization with median, quartiles, whiskers, and caps properly
+    constructed
+  - Jitter and transparency on strip points effectively reduce overlap
+  weaknesses:
+  - Grid only shows on y-axis, no x-axis guides (minor visual consistency issue)
+  - Some strip points in dense areas still overlap slightly despite jitter
