This visualization displays a map of the United States with state boundaries rendered as blue filled polygons with orange strokes, using the geoAlbersUsa projection via d3.geoPath. It loads TopoJSON data from the US Atlas TopoJSON repository, converts it with topojson.feature, and appends SVG path elements for each state. Hovering over a state changes its fill to red, while geographic graticules are included in the styling. The map is built with D3 v5 and rendered as SVG.
