This interactive map displays the 50 U.S. states as red land areas with black borders, using a geographic projection. The visualization relies on `d3.geoPath` with the `geoAlbersUsaTerritories` projection to render the map from TopoJSON data loaded via `d3.json` and the `topojson` library’s `feature` and `mesh` functions. React manages the component state and SVG rendering, while CSS hover styling changes state colors from red to blue. The map refreshes its data asynchronously, initially showing a loading message before presenting the full geographic layout.
