{"version":"1.0","type":"rich","title":"Leaflet multilayer example | CartoDB.js","description":"A Leaflet map displays tornado data aggregated into hexagon bins at three distinct scales, with each bin labeled by its point count. The visualization uses CartoDB.js to run a SQL query that computes three nested hexagon grids, filtering points into large, medium, and small clusters based on density thresholds. A CartoDB sublayer applies CartoCSS to scale text sizes by cluster tier, overlaying the raw points with red labels on a Stamen toner base layer.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-8306637?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
