{"version":"1.0","type":"rich","title":"Choropleth Map","description":"A choropleth map of the United States visualizes total earthquakes per state on a geographic projection, using a color scale that encodes the logarithmic earthquake count. State regions are colored according to their assigned region, with a sequential color scheme from `schemeOrRd`. The map is rendered as SVG paths using `d3.geoPath` with a `geoAlbersUsa` projection, and earthquake data is loaded from a CSV file. Hovering highlights a state in light green with a dark red stroke.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/845d4a18ac264c448e24025ca2458e0f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
