{"version":"1.0","type":"rich","title":"CartoDB Point Clustering","description":"This example displays a choropleth map of U.S. ZIP code tabulation areas, colored by the ratio of mortgage disclosures to brokers, with polygon opacity scaled by broker count. It uses CartoDB.js with Leaflet to render the map, an SQL query joining broker data to census geographies, and CartoCSS for the graduated color and opacity styling. The map applies an aggregation stack blur filter to smooth the rendered polygons.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-f16c88ecd8d151eae384?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
