This choropleth-style map displays all 50 US states using an orange fill with black state boundaries, highlighting individual states in green when hovered. The visualization loads geographic data from a TopoJSON file via `useData()`, then renders it as SVG paths using `d3.geoPath()` with the `geoAlbersUsaTerritories()` projection. Built with React and D3 v5, the code integrates TopoJSON's `feature()` and `mesh()` functions to generate land polygons and interior borders.
