This example displays a map of U.S. states filled with a teal color, rendered as SVG paths inside a React component. It uses the `d3.geoAlbersUsa` projection and `d3.geoPath` to convert TopoJSON state boundaries from the `us-atlas` dataset into visible shapes. The map is drawn within a React app that loads the data asynchronously via `useEffect` and the D3 `json` function, while the `topojson.feature` API extracts the state geometries.
