{"version":"1.0","type":"rich","title":"Map","description":"This visualization presents a choropleth map of U.S. county-level unemployment rates, where each county is colored according to its rate using a quantile color scale from the Inferno palette. The map uses D3's `geoPath` and `geoAlbersUsaTerritories` projection to render county and state boundaries from TopoJSON data. A linked histogram at the bottom allows for interactive brushing to highlight counties within a selected unemployment rate interval. The example demonstrates the D3 General Update Pattern for dynamic styling and attribute updates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/97155d4e9faf4a4cb70fe7b06d3ea13e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
