This visualization maps reapportionment of U.S. House seats after the 2020 census, using a geographic projection with state polygons and circular seat icons. Each state’s seats appear as rings whose radii reflect population per seat in 2010 and 2020, with colors indicating maintained, added, or removed seats. It uses `d3.geoAlbersUsa`, `d3.geoPath`, and `d3.scaleSqrt` on an SVG canvas, pulling polygon, centroid, and apportionment data from Census sources via GitHub gists.
