This example displays a choropleth-style map of the United States, using green landmasses against a pale blue sphere and bright blue state boundaries. It renders the nation’s exterior and internal state borders as SVG paths, with a graticule overlay for geographic reference. The visualization is built with React, pulling TopoJSON data from the us-atlas package, and relies on d3’s geoAlbers, geoPath, and geoGraticule APIs to project and draw the map.
