This example displays a choropleth-style map of the United States using an Albers USA projection with territories via `geo-albers-usa-territories`. The visualization renders land polygons in sky blue and state boundary interiors in green, with the path geometries generated by `d3.geoPath`. React manages the component structure, while `d3.json` loads the TopoJSON data and `feature` and `mesh` from the `topojson` library extract the land and interior boundaries. The map focuses on geographic shape rather than quantitative values, using a simple two-color scheme for clear visual separation.
