{"version":"1.0","type":"rich","title":"Earthquake Choropleth Map","description":"A choropleth map of the United States visualizes the logarithmic count of total earthquakes by state, with counties colored using a threshold-based scale from the d3.schemeOrRd sequential color scheme. The map is rendered as an SVG, with each state drawn via the d3.geoPath projection. Hovering over a state triggers a tooltip, implemented with a custom d3.tip, that displays the state name, region, and earthquake count. The geographic boundaries and earthquake data are loaded from TopoJSON and CSV files, respectively.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/21ed08b8713945e983a487d6419fca0d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
