A choropleth-style map displays the contiguous United States with state boundaries, rendered in SVG using React. The visualization uses `d3.geoAlbers` for projection and `d3.geoPath` to draw geographic features, with `d3.geoGraticule` generating graticule lines. Land areas are filled pink, interiors stroked darkblue, and the sphere background is yellow, styled via CSS. Geographic data comes from the US Atlas TopoJSON, processed with `topojson.feature` and `topojson.mesh`.
