This example renders a polished map of the United States using D3’s `geoAlbers` projection and `geoPath` to draw state boundaries and graticules. TopoJSON data from the US Atlas (`states-10m.json`) is loaded via `d3.json`, with `feature` and `mesh` extracting land and interior borders. React manages the SVG output, styling the land in white, sphere in blue, and interiors in red. The visualization highlights geographic boundaries with a clean, minimal aesthetic.
