- Theme-adaptive basemap style switching (carto-positron vs carto-darkmatter) integrates
19
+
seamlessly with the light/dark theme system
20
+
- 'Perfect spec compliance: density heatmap, basemap, colorbar, transparency, interactivity
21
+
all present and working'
22
+
- Real SF Bay Area data with four geographically accurate hotspots creates an immediately
23
+
interpretable visualization
24
+
- Clean flat code with all theme tokens properly applied to colorbar elements
25
+
- HTML export provides interactive output alongside PNG renders
26
+
weaknesses:
27
+
- YlOrRd colorscale is valid per spec but not the style guide default (viridis preferred);
28
+
yellow-end has lower CVD safety compared to viridis — switch to colorscale=Viridis
29
+
- 'Design sophistication (DE-01=5/8): no focal-point annotation on highest-density
30
+
hotspot, no colorbar frame styling using ELEVATED_BG token'
31
+
- Map tile text cannot be resized by implementation, slightly limiting VQ-01

Light render (plot-light.png):
34
+
Background: Warm off-white carto-positron basemap with paper_bgcolor ~#FAF8F1 border area; basemap itself is light grey/white tile style
35
+
Chrome: Title "Activity Density · heatmap-geographic · python · plotly · anyplot.ai" at 28px in dark INK color — clearly readable; colorbar title "Intensity" at 20px, tick labels at 16px in INK_SOFT — all readable
36
+
Data: YlOrRd colorscale with opacity=0.7; four hotspots visible (Downtown SF largest/most intense in red, Oakland, Berkeley, South SF); background scatter in yellow; color gradient clearly shows density variation
37
+
Legibility verdict: PASS
38
+
39
+
Dark render (plot-dark.png):
40
+
Background: Near-black carto-darkmatter basemap with paper_bgcolor ~#1A1A17 border area; basemap itself is dark tile style
41
+
Chrome: Title text in light INK color (#F0EFE8) — clearly readable against dark background; colorbar title and ticks in INK_SOFT (#B8B7B0) — readable; map tile city labels appear in light/white text; NO dark-on-dark failures
42
+
Data: YlOrRd colorscale colors are identical to light render (same yellow→red gradient hotspots); data colors unchanged, only chrome flipped; hotspots pop vividly against the near-black basemap
