 review:
-  strengths: []
-  weaknesses: []
+  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
+  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
+  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.'
