This example displays a choropleth-style map of the United States with light green states outlined in orange on a light blue background. It uses d3.geoPath with a d3.geoAlbersUsa projection to render the map, and topojson.feature to extract state boundaries from the US Atlas states-10m.json dataset. The visualization is drawn as an SVG with a fixed width and height, with each state path filled and stroked directly.
