This map displays the 50 states of the USA, using a purple fill for each state with black borders and a hover effect that turns states pink. It renders geographic data with `d3.geoPath` and the `geoAlbersUsaTerritories` projection, processing TopoJSON from the `us-atlas` package. The visualization is built with React and D3 v5, using `useData` to fetch and transform the data, and renders as an SVG via the `Marks` component.
