This interactive SVG map displays the fifty US states in a muted orange with white borders, using an Albers equal-area projection. It loads TopoJSON state boundaries from the `us-atlas` package, converts them to GeoJSON features with the `topojson.feature` API, and renders them via `d3.geoPath`. Mousing over a state highlights its border and triggers a semi-transparent tooltip showing the state’s name, positioned near the cursor using the `d3.select` and event handling code.
