This choropleth displays the 50 U.S. states on an SVG map, using a pink fill for each state and white borders to delineate the interiors. Built with React and D3 v5, it employs the `geoAlbersUsaTerritories` projection and `d3.geoPath` to render the geographic features loaded from the `us-atlas` TopoJSON source. Hovering over a state changes its fill to orange.
