The visualization uses D3 v5’s `geoAlbersUsa` projection and `geoPath` to draw county boundaries from TopoJSON data loaded from the us-atlas package. County shapes are styled with black strokes and a green fill on mouseover, showing the geographic distribution of administrative divisions. The code filters the TopoJSON for county features and binds them to path elements, relying on the browser’s built-in tooltip behavior for the name display.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ddd78b0003f7473caa5b2743c03fddbb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
