This example displays a map of the 50 US states, with each state filled in red and white borders separating them. The visualization uses the `geoAlbersUsaTerritories` projection and the `d3.geoPath` API to render geographic shapes as SVG paths. The map is generated from TopoJSON data loaded from a remote US atlas source, and it enhances interactivity by changing each state’s color to green when the pointer hovers over it.
