{"version":"1.0","type":"rich","title":"CartoDB Point Clustering","description":"This example uses CartoDB to render U.S. state polygons with clustered point data. Clicking a state triggers an SQL query that applies ST_Dump and ST_SimplifyPreserveTopology to generate line segments radiating from the state centroid to its boundary points, producing a stylized \"POW!\" label effect. The visualization combines CartoDB’s tile layer API with custom CartoCSS styling, including pattern fills and text labels, to show how dynamic SQL can reshape geographic features interactively.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-242b7511df018a67f807?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
