# Maps

Confirm that geography answers the question. Record source date, coordinate system, projection and attribution. Use SVG/D3 Geo for small static geography, MapLibre for tiled navigation, deck.gl for dense GPU layers. Avoid area comparisons without normalization. Provide a table or list alternative and mobile interaction path. `fixtures/map` is the static-map probe; do not misrepresent it as a tiled map.
