This example displays a map of the United States with each state rendered as a tan SVG path with grey borders on a blue ocean background. The visualization loads US Atlas TopoJSON data and converts it to GeoJSON features using `topojson.feature`, then projects the coordinates with `d3.geoAlbersUsa` and `d3.geoPath` within a React component. Hovering a state changes its fill color to dark green. The code references commented-out scales and data joins for potential color mapping, though the active version only renders the base geography.
