This example displays a map of the United States with state boundaries, rendered as SVG paths using D3’s `geoAlbers` projection and `geoPath`. It shows land areas in blue, a graticule sphere in purple, and state interiors highlighted with yellow strokes. The map loads US Atlas TopoJSON data from jsdelivr, processes it with `topojson.feature` and `topojson.mesh`, and is built within a React component using the `geoGraticule` API to draw the graticule lines.
