 review:
   strengths:
-  - 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
+  - Excellent geological context with real Grand Canyon formation data and accurate
+    stratigraphy
+  - Strong visual hierarchy with bold formations, italic ages, and red unconformity
+    focal points
+  - Clean declarative Altair code with well-organized layer composition
+  - Good use of age brackets and unconformity markers to organize the geological narrative
+  - Professional color palette with colorblind-safe distinct lithology colors
   weaknesses:
-  - 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 (top) to 200m (bottom) depth. Each layer is a colored rectangle:
-    Sandstone in yellow (#F5D76E), Shale in gray (#7B8D8E), Limestone in blue (#5DADE2),
-    Siltstone in purple (#C39BD3), and Conglomerate in orange (#E67E22). Inside each
-    rectangle, text-based pattern symbols indicate lithology (dots for sandstone,
-    dashes for shale, grid squares for limestone, short dashes for siltstone, circles
-    for conglomerate). 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) appear in bold to the right of each layer. Age labels (Permian, Pennsylvanian,
-    Mississippian, Devonian, Cambrian) appear in italics on the left side. Dashed
-    horizontal lines mark geological period boundaries. The Y-axis shows "Depth (m)"
-    with depth increasing downward. A horizontal legend at the bottom identifies the
-    5 lithology types. Title reads "column-stratigraphic · altair · pyplots.ai" at
-    the top.'
+  - Text-based pattern approximations are less distinct than true geological hatching
+    (Altair limitation)
+  - Column width could be wider to better fill the horizontal canvas space
+  - Minor visual crowding near unconformity labels where they overlap with pattern
+    text
+  - Thickness variation in layers is modest (15-25 m range)
+  image_description: 'The plot displays a vertical stratigraphic column of the Grand
+    Canyon sedimentary section spanning Cambrian to Permian periods. Ten geological
+    layers are shown as colored horizontal rectangles stacked vertically with depth
+    increasing downward (0-200 m). Colors used: yellow (Sandstone), gray (Shale),
+    blue (Limestone), purple (Siltstone), orange (Conglomerate). Each layer has text-based
+    pattern overlays approximating geological symbols (dots for sandstone, dashes
+    for shale, squares for limestone, dashes for siltstone, circles for conglomerate).
+    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
+    to the right in bold. Thickness annotations (15 m, 20 m, 25 m) appear on the far
+    right in italic gray. Age period labels (Permian, Pennsylvanian, Mississippian,
+    Devonian, Cambrian) are on the left with vertical bracket lines. Two red dashed
+    unconformity lines appear at depths 110 and 155 m with labels. The title reads
+    "column-stratigraphic · altair · pyplots.ai" with subtitle "Grand Canyon Sedimentary
+    Section — Cambrian to Permian". A horizontal legend at the bottom shows all 5
+    lithology types. Background is light gray.'
