This map displays the fifty U.S. states as orange landmasses with black state borders, highlighting a state in green when hovered. It loads geographic data from a TopoJSON file hosted on unpkg, processes it with `topojson.feature` and `topojson.mesh`, and projects it using `geoAlbersUsaTerritories`. The React component renders the map as SVG paths via `d3.geoPath`, with loading state handled by React hooks.
