This example displays a map of the United States, rendered with orange state boundaries against a blue ocean background. The visualization uses D3 v4’s `d3.geoPath` and `d3.geoAlbersUsa` projection to draw the states from TopoJSON data loaded via `topojson.feature`. The map is positioned within an SVG container, with styling applied through CSS. The code reads the us-atlas states-10m dataset from a CDN and draws each state as a separate path element.
