This example displays a stylized map of the United States, showing state boundaries and graticules over a colored sphere. The visualization uses React with D3 v5 to fetch TopoJSON data from the us-atlas package, converting it to map features via the `d3.feature` and `topojson.mesh` APIs. It renders land masses in teal, interiors in blue, and graticule lines in gray using SVG paths generated by `d3.geoPath` and the `geoAlbers` projection.
