This example displays a stylized map of the United States with state boundaries, rendered in an SVG using React. It loads geographic data from the US Atlas TopoJSON via `d3.json` and uses `topojson.feature` and `topojson.mesh` to extract land and interior borders. The `d3.geoAlbers` projection and `d3.geoPath` draw the shapes, with `d3.geoGraticule` defined but unused in the final marks. The map is colored with teal land, a light blue sphere, and purple state boundaries, showcasing a clean, polished visual style.
