{"version":"1.0","type":"rich","title":"County Choropleth","description":"This visualization is a county-level choropleth map of the unemployment rate across the United States, using data from August 2016. The map is rendered with an Albers equal-area projection that includes all US territories, drawing county boundaries with `d3.geoPath` and colored using a quantile scale with the Inferno color palette via `d3.scaleQuantile` and `d3.interpolateInferno`. Counties with missing data appear red, while state boundaries are stroked in white. The implementation uses `d3.select` and `.join` for idempotent rendering, with `getUSAtlasData` fetching GeoJSON from the `us-atlas` package and `d3.json` for data loading.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/46ae41162058471ea5d3b6a949da2ce1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
