Maps & Geospatial

3 components · sorted by setup time

Put it on a map. Judges remember what they can see.

Why it matters

Geographic visualization turns abstract data into something anyone can understand immediately. Climate, food, civic, transit, health — almost every impact domain has a location component. A map makes your project's scope and impact legible in seconds. Winning civic and climate projects almost always have a map.

⚠ common pitfall

Don't add a map just to have a map. If location isn't core to your problem, skip it. A bad map clutters the demo more than no map.

✦ how to choose

react-leaflet for quick, open-source maps with no API key needed. Mapbox GL JS when you need custom styling or vector tiles. Deck.gl for large datasets or 3D visualization. Start with react-leaflet — you can swap later if you need more power.
