This example displays a choropleth-style map of the United States rendered as SVG paths, using React to manage component state and the d3.geoAlbersUsa projection with d3.geoPath to draw state boundaries from TopoJSON data loaded via the us-atlas package. The map is populated with geospatial features fetched from a remote URL, while a loading fallback appears until the data arrives. The visualization emphasizes the geographic outlines rather than quantitative values, with a single teal fill applied to all marks.
