{"version":"1.0","type":"rich","title":"Fork of Choropleth with Histogram Brushing","description":"This visualization shows the unemployment rate for U.S. counties in 2022 using a choropleth map paired with a brushable histogram. The map colors each county by quantile, while brushing a range on the histogram highlights matching counties and dims others. Built with vanilla JavaScript and D3, it uses `d3.geoPath` for map rendering from `us-atlas` TopoJSON data and `d3.scaleQuantile` for color mapping, with zooming via `d3-rosetta`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b765dac3368c4205a933315c7cde6c65?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
