{"version":"1.0","type":"rich","title":"Fork of Choropleth with Histogram Brushing","description":"This interactive visualization displays the August 2016 unemployment rate for U.S. counties on a choropleth map, using a quantile color scale with d3.scaleQuantile and the Inferno interpolator. A brushable histogram below the map, built with d3.bin and d3.brushX, allows filtering highlighted counties by rate, with non-selected areas grayed out via d3-rosetta utilities. The map supports zooming, uses topojson-client for county boundaries, and renders with d3.geoPath and the geo-albers-usa-territories projection.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f386457d72dc4b428ba0a8b3a565aab5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
