This example displays a choropleth-style map of the United States, with each state filled in green and outlined in a semi-transparent orange. It shows the geographic boundaries of all 50 states, highlighting them in red on hover. The visualization uses the D3 v5 library with `d3.geoPath` and `geoAlbersUsa` projection, rendering the map as SVG paths from TopoJSON data loaded from the us-atlas repository. The `states-10m.json` file provides the geographic features, and the `geo-albers-usa-territories` plugin enables territory inclusion.
