The map uses the `geoAlbersUsa` projection and `geoPath` from D3 v5, while TopoJSON’s `feature` method extracts county geometries from the us-atlas counties-10m.json dataset. Hovering highlights the county in green via a CSS `:hover` rule. The visualization depends on D3’s `select` and `json` utilities to fetch and bind the geographic data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b4702a2bfb3e4799958710840e4a06b3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
