This example displays a stylized map of the United States, showing state boundaries and graticules, with land areas shaded and states that highlight on hover. Built with React and D3 v6, it uses `geoAlbersUsa`, `geoPath`, and `geoGraticule` to project and render the map. Data comes from the US Atlas TopoJSON, processed via `feature` and `mesh` from topojson, and is drawn as SVG paths with CSS styling for visual polish.
