This visualization displays a map of the United States using an Albers equal-area conic projection. It shows landmasses, state boundaries, and a sphere outline, with states rendered in light blue and internal borders in teal against a white background. The code uses React to manage data loading via useEffect and useState, fetching GeoJSON from a TopoJSON file via d3.json. D3’s geoPath and geoAlbers generate SVG paths, while topojson’s feature and mesh functions extract nation boundaries and state interiors for rendering.
