This visualization displays the United States as a single violet country shape on a green background, rendered using an SVG path. It loads world map data from the World Atlas TopoJSON file and uses `d3.geoAlbersUsa` with `d3.geoPath` to project and generate the path. The topojson `feature` method extracts country boundaries, then filters the data to keep only the United States before appending it to the SVG.
