{"version":"1.0","type":"rich","title":"CartoDB Point Clustering","description":"This example displays point clustering on an interactive map centered on New Orleans, using CartoDB and Leaflet. It shows a sublayer of Twain dataset points filtered by city name, rendered as large blue markers. Clicking a marker queries overlapping points via CartoDB’s SQL API, revealing their count and source values in a side panel. The map uses Stamen toner tiles, while hover interactions change the cursor through CartoDB’s `featureOver` and `featureOut` events.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-7b5722c47487c8b67a88?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
