{"version":"1.0","type":"rich","title":"Earthquakes since 1965","description":"This world map displays significant earthquakes since 1965, using circles sized by magnitude, with tooltips showing country and magnitude. The visualization renders on an SVG canvas using React and D3 v5, employing `geoNaturalEarth1` projection with `geoPath`, `geoGraticule`, and world atlas TopoJSON for land boundaries. Earthquake data comes from a cleaned CSV of the Kaggle USGS dataset. Semi-transparent red circles encode magnitude through a square-root scale, overlaid on light blue oceans and green landmasses.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ab189a6d9b994a63bd2dff2983a7d9af?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
