{"version":"1.0","type":"rich","title":"Choropleth with Histogram Brushing","description":"This interactive data visualization displays the unemployment rate by U.S. county for August 2016. A choropleth map uses a quantile color scale with four bins, rendered via `d3.geoPath` and the `geo-albers-usa-territories` projection. A linked histogram below the map, built with `d3.bin` and `d3.brushX`, allows users to brush a range of values, which highlights matching counties on the map while dimming others. The visualization also supports zooming through the `d3.zoom` utility, with map rendering optimized using memoization.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9ac8ce4b6d7f412db1a918454a2f399b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
