City portal coverage choropleth
The four host counties color-band by curated dataset count or by water-themed datasets only. Empty counties simply have no city open-data portal yet — not zero open data.

Correlation prompts
Read this layer like a lead, not a leaderboard.
- •Flip between metric modes to see which counties stay bright across unrelated burdens versus which only flare in one layer.
- •Use overlays to isolate counties where the highlighted pattern may explain why a metric spikes or refuses to move.
- •Check the top list for repeat names, then trace whether they cluster geographically or break the regional pattern.

The choropleth uses host-county centroids only — it does not imply that the dataset coverage is geographically scoped to that county alone. Many city datasets cover their broader metro footprint.

Planned follow-on layers
- Per-dataset Atlas ingestion laneSurface which curated datasets have an Atlas refresh script attached vs. which are still discovery-only.
- County / regional portal coveragePull TCEQ regional, GBRA, LCRA, and Texas state agency portals into the same curated discovery view.
- Recency overlayColor portals by their most-recently updated water-themed dataset to flag stale catalogs.
- Format mix barsBar charts for JSON / CSV / Shapefile / API formats per portal so analysts know what they can pipe straight into Atlas.
