This visualization displays U.S. states as a choropleth map, highlighting a subset of selected state IDs in orange while rendering all others in gray. It uses D3 v5’s `geoAlbersUsa` projection and `geoPath` to draw SVG paths from TopoJSON data loaded from `us-10m.v1.json`. The code filters state features against a predefined set and applies the `.selected` CSS class, though the commented-out section means the highlighting is not rendered in the final output.
