 review:
-  strengths: []
-  weaknesses: []
+  strengths:
+  - Excellent geological data with realistic formation names, ages, and stratigraphic
+    sequence
+  - Custom earthy color palette appropriate for geological visualization
+  - Good use of lets-plot interactive tooltips (layer_tooltips) showing depth, thickness,
+    formation, and age on hover
+  - Clean code structure with deterministic data and proper file management
+  - Age boundary dashed lines effectively separate geological periods
+  weaknesses:
+  - Missing lithology fill patterns (hatching/textures) which is a key spec requirement
+  - Canvas utilization could be improved - the column is narrow relative to total
+    canvas width
+  - Sandstone and Siltstone colors are similar, potentially hard to distinguish
+  - geom_text font size (10) is slightly small for formation and age labels
+  image_description: 'The plot shows a vertical stratigraphic column with 10 geological
+    layers stacked from 0m to 260m depth (increasing downward). Each layer is a colored
+    rectangle with black borders: Sandstone in yellow/gold, Shale in gray, Limestone
+    in blue, Siltstone in tan/beige, and Conglomerate in coral/red. Formation names
+    (e.g., "Basal Sand Fm", "Reef Limestone Fm") are labeled to the right of each
+    layer. Geological age labels (Triassic, Jurassic, Cretaceous, Paleogene) appear
+    on the left side. Dashed horizontal lines mark age boundaries at 35m, 110m, and
+    195m. The y-axis reads "Depth (m)" and the x-axis is hidden. A horizontal legend
+    at the bottom shows all 5 lithology types. Title reads "column-stratigraphic ·
+    letsplot · pyplots.ai". The overall layout is clean with a minimal theme, subtle
+    y-grid, and generous whitespace, though the column occupies only a moderate portion
+    of the canvas width.'
