{"version":"1.0","type":"rich","title":"yi xiao Map","description":"This choropleth map visualizes the logarithm of total earthquake counts per U.S. state, using an ordinal color scale with nine shades from the `schemeOrRd` spectrum. Built with D3 v5 and the `topojson` library, it projects state boundaries via `geoAlbersUsa` and renders them as SVG paths. Hovering a state changes its fill to light green and displays a tooltip with the state name, region, and raw earthquake total, sourced from a CSV dataset joined to a TopoJSON file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3a462410a2f64d50a7de8ff4e304cb62?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
