This visualization displays a choropleth-style map of the United States using an Albers equal-area conic projection. The map shows landmasses in a light red fill, state boundaries as purple interior lines, and a gray sphere background, with graticule lines. Built with React and D3 v5, the code uses `d3.geoAlbers` for projection, `d3.geoPath` to generate SVG paths, and TopoJSON’s `feature` and `mesh` methods to process US Atlas state data. The map renders at 2000×600 pixels within an SVG container.
