07_filter_map standalone app

Run

cd 00_Proposal/07_filter_map
python -m pip install -r requirements.txt
python app.py

Then open http://127.0.0.1:5050.

PythonAnywhere Notes

1. Install dependencies from requirements.txt (includes flask-compress for gzip JSON responses).
2. Configure static files to serve 00_Proposal/07_filter_map/static at /static/.
3. The app now uses progressive overlay loading:
   • /api/bootstrap loads core map data only.
   • overlay GeoJSON is fetched lazily via /api/overlay/<layer_id>.
4. First cold start can still take longer while DataStore.load() warms caches; warm requests are much faster.
5. For paid plans, a periodic ping to /health can reduce cold-start delay.

Notes

1. UI uses Comfortaa from Google Fonts.
2. Monochrome control styling with accent #FBD124.
3. Bivariate fill colors remain data-driven.
