This example displays a map of the United States, rendered as an SVG using a React component. It shows the nation’s land area in green, state boundaries as black lines, and an orange sphere background. The code employs D3’s `geoAlbers` projection and `geoPath` to draw geographic features, with `geoGraticule` available for reference lines. TopoJSON data from the `us-atlas` repository is loaded via `d3.json`, and the `feature` and `mesh` functions extract the landmass and state interiors.
