{"version":"1.0","type":"rich","title":"Zoomable County Choropleth","description":"This example visualizes unemployment rates across U.S. counties from August 2016 using a digital choropleth map. The map, rendered with `d3.geoPath` and a `geoAlbersUsaTerritories` projection, colors each county using a `scaleQuantile` with `interpolateInferno`. It supports interactive zooming and panning via `d3.zoom`, with `d3-rosetta` managing state and efficient DOM updates. County boundaries and state meshes come from the `us-atlas` TopoJSON dataset, while the unemployment figures are loaded from a local CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a4f14978e49744cda77ee4094334df2c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
