{"version":"1.0","type":"rich","title":"Ver3 Earthquakes (past 30 days)","description":"This visualization displays global earthquake activity from the past 30 days on an interactive world map. Circles are positioned using a D3 geoEquirectangular projection, with circle size encoding earthquake magnitude. Color encodes depth, with red for shallow (<70km), green for intermediate (70-300km), and blue for deep (≥300km) earthquakes. The map also shows country boundaries, graticules, and tectonic plate boundaries. Users can click any earthquake circle to open its USGS details page in a new tab, or pan and zoom using the d3.zoom() interaction. Additional brush-based zooming is implemented to allow for more intuitive exploration of the data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d1d19c31db064045b9fdf40949c7c544?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
