{"version":"1.0","type":"rich","title":"Easy earthquakes","description":"A user’s geolocation triggers a real-time map animation of earthquakes, shown as expanding colored circles on a dark Mercator projection of world borders. The visualization pulls geographic data from CartoDB via SQL queries, using `cartodb.SQL` to fetch user locations and map features, while D3.js renders SVG paths and animated circles. Circle color encodes earthquake category through a logarithmic scale, and each pulse expands and fades over two seconds before repeating, with zoom and pan supported via `d3.behavior.zoom`.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-4726570?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
