{"version":"1.0","type":"rich","title":"activity 6_Task 1","description":"This interactive map of global earthquake activity reveals the network of seismic events over time, with circles sized by magnitude and colored by depth. The visualization uses D3.js’s `d3.select` and `d3.scale` for data-driven encodings, while geographic boundaries are drawn via `d3.geoPath` from GeoJSON data. Earthquakes are rendered as animated points summoned from the USGS live feed, highlighting the planet’s restless tectonic boundaries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f6a27c6255f346949d3a0d1ecfcc3f9b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
