{"version":"1.0","type":"rich","title":"yi xiao Map","description":"A choropleth map of the United States shows the total number of earthquakes per state, colored on a sequential logarithmic scale using an ordinal scale with the `schemeOrRd` color ramp. The map is rendered with `d3.geoPath` and the Albers USA projection, using TopoJSON state boundaries and CSV data loaded via `d3.csv`. Hovering a state highlights it in green and displays a tooltip via SVG `title` elements listing the state name, region, and earthquake count. The visualization uses D3 v5 and includes a custom `colorLegend` component to explain the color scale.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/45bbba87d9504b20bd478438ad217bdd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
