{"version":"1.0","type":"rich","title":"Earthquake Choropleth Map","description":"This choropleth map visualizes the distribution of total earthquakes across U.S. states, using a logarithmic color scale based on d3.scaleThreshold and the d3.schemeOrRd sequential color scheme. It renders each state as an SVG path via d3.geoPath with a d3.geoAlbersUsa projection, pulling geographic boundaries from TopoJSON and earthquake counts from a CSV. Hovering highlights states with a red stroke, while a d3-tip tooltip is intended to display state name, region, and earthquake count.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/391841346cc140fa9ad1f4be0a89c9bf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
