This example displays a map of the United States with state boundaries, rendered as an SVG using React and D3. The visualization loads US Atlas TopoJSON data from a CDN and projects it using the `geoAlbers` projection, drawing landmasses with `geoPath`. State interiors are highlighted as black lines, generated from the `mesh` function from the topojson library, while the overall map is styled with a purple fill for land and a white sphere background.
