 review:
   strengths:
-  - Excellent realistic geological data using real Grand Canyon formations and correct
-    ages
-  - Clean code structure with good use of Altair declarative layered composition
-  - Custom geologically-conventional color palette with intentional typography hierarchy
-  - Tooltips with formation, lithology, age, and thickness information
-  - Age boundary dashed lines add professional geological context
+  - Excellent use of real Grand Canyon geological formation names creating highly
+    realistic and educational data
+  - Clean layered composition using Altair declarative + operator for rects, patterns,
+    labels, and age boundaries
+  - Thoughtful domain-appropriate color palette with geologically conventional associations
+  - Good typography hierarchy with bold formations, italic ages, and regular patterns
+  - Full interactivity support via tooltips and HTML export
   weaknesses:
-  - Depth axis is inverted - spec requires depth increasing downward but plot shows
-    upward
-  - Title format includes extra Stratigraphic Column prefix beyond required format
-  - Siltstone and Limestone colors are both blue tones and hard to distinguish
-  - Pattern symbols are faint at 0.6 opacity and do not effectively convey lithology
+  - Text-based pattern symbols are small and do not fully replicate geological lithology
+    fill patterns
+  - Age labels at 15pt could be slightly larger for better readability
+  - No visual emphasis on geological transitions or unconformities to enhance data
+    storytelling
+  - Color palette could be optimized for colorblind accessibility
   image_description: 'The plot shows a vertical stratigraphic column with 10 geological
-    layers stacked from 0m (bottom) to 200m (top). Each layer is a colored rectangle
-    representing a lithology type: Sandstone (golden yellow), Shale (gray), Limestone
-    (blue), Siltstone (light blue), and Conglomerate (orange). Formation names (Cedar
-    Mesa Fm, Organ Rock Fm, White Rim Fm, De Chelly Fm, Coconino Fm, Hermit Fm, Supai
-    Group, Redwall Fm, Temple Butte Fm, Muav Fm) are labeled in bold to the right
-    of each layer. Geological age labels (Permian, Pennsylvanian, Mississippian, Devonian,
-    Cambrian) appear in italics on the left side. Dashed horizontal lines mark age
-    boundaries between geological periods. Text-based pattern symbols (dots, dashes,
-    squares, circles) are rendered inside each layer at reduced opacity. A horizontal
-    legend at the bottom shows all 5 lithology types with colored swatches. The title
-    reads "Stratigraphic Column · column-stratigraphic · altair · pyplots.ai" at the
-    top. The y-axis is labeled "Depth (m)" with tick marks every 10m. Depth increases
-    upward (0 at bottom, 200 at top), which is contrary to the spec requirement.'
