This visualization displays a United States map with state boundaries rendered in tan and outlined in black, with a hover effect that turns each state white. It uses D3 v5 with the `geoAlbersUsa` projection and `geoPath` to draw SVG paths from TopoJSON county data loaded from the us-atlas package. The map is created by selecting all paths and binding them to state features, with a `title` element added for each state to show its name. The interaction is implemented via CSS `:hover` styling rather than JavaScript event handlers.
