{"version":"1.0","type":"rich","title":"CartoCSS for Animated Bubble Map","description":"CartoCSS drives an animated bubble map of crime incidents, showing how event density changes over time. The visualization uses Torque’s time-based rendering with 72 frames over a 30-second duration, aggregating counts from the `fromdate` attribute. Bubble sizes scale progressively when aggregated values exceed thresholds (2, 8, 16), with an XOR composite operation blending overlapping markers. The map relies on CartoDB’s Torque API and CartoCSS styling, referencing `cartodb_id` for counting, while marker properties like fill color, line width, and ellipse shape are defined in the stylesheet.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-18c1640d41cc7a07da7f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
