This example displays a choropleth-style map of U.S. states, with land areas filled in orange and interior borders stroked in green. It uses React and D3 v5, employing `d3.geoPath` with the `geoAlbersUsaTerritories` projection, along with TopoJSON’s `feature` and `mesh` functions to generate the land and boundary paths from a remote JSON file. The map is rendered as an SVG, with marks drawn via a React component.
