This choropleth-style map displays the United States with state boundaries and a shaded landmass, rendered as SVG paths within a React component. The visualization uses `d3.geoAlbers` and `d3.geoPath` to project and draw geographic features from TopoJSON data loaded via `d3.json` from the us-atlas repository. State borders are derived using `topojson.mesh`, while the land and sphere shapes are filled in contrasting colors. The map is displayed at 1000 by 600 pixels, with loading state handled through React hooks.
