This map of the United States displays state boundaries using a custom geoAlbersUsaTerritories projection from the geo-albers-usa-territories library. React renders SVG paths generated by d3.geoPath, with land filled in light yellow and state interiors stroked in blue. The visualization loads geographic data from the us-atlas TopoJSON dataset, using topojson.feature() and topojson.mesh() to extract land masses and internal borders. A graticule layer, defined by d3.geoGraticule, appears in yellow, though it is not explicitly rendered in the current marks.
