This example displays a choropleth-free map of the United States rendered as SVG, using a light gray sphere background with white landmasses and dark interior borders. It loads TopoJSON data from a GitHub gist, converting it to GeoJSON via `feature` and `mesh` from topojson. The visualization employs React for component structure and state management, while D3’s `geoAlbers` projection and `geoPath` generate the geographic paths. The code also defines a graticule but does not render it in the final output.
