{"version":"1.0","type":"rich","title":"Choropleth w/ state highlighting","description":"This choropleth displays U.S. county unemployment rates colored on a quantize scale from light to dark blue, overlaid with white state boundary lines. When hovering over a county, its outline turns red and all counties outside that county’s state fade to 50% opacity, using CSS classes generated from the state FIPS code to highlight the state containing the hovered county. The map uses an Albers USA projection and is built with D3 v3 and TopoJSON, with county fill colors mapped from unemployment data.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-304a777b08ab05b64c04839034991fb7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
