Examples

Multi-layer, map-backed visualizations using real public datasets. Each example downloads live data, builds layers, and renders an interactive deck.gl map.

Global Flight Routes

Airline routes between the world’s 40 busiest airports from the OpenFlights database, rendered as great-circle arcs with labeled airport markers on a dark basemap.
