{"version":"1.0","type":"rich","title":"Easy earthquakes","description":"The visualization animates a chronological sequence of earthquakes on a world map, with each quake appearing as a red circle that expands and fades based on its magnitude. It shows earthquake locations and relative strengths over time, looping through the dataset repeatedly. The map uses a d3.geo.mercator projection with d3.geo.path to render world borders from CartoDB’s SQL API, while earthquake data is fetched via `cartodb.SQL` and drawn as SVG circles with d3 transitions. Zooming and panning are enabled through `d3.behavior.zoom`.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-4534319?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
