{"version":"1.0","type":"rich","title":"yi xiao Map","description":"This choropleth map visualizes the total number of recorded earthquakes per U.S. state, using a logarithmic transformation of the raw counts to compress the data’s range. The map is rendered in SVG using d3.geoPath with a geoAlbersUsa projection, while a d3.scaleOrdinal maps logged earthquake values to a nine-step sequential color scheme from schemeOrRd. State boundaries are drawn from TopoJSON data, and each state includes a title tooltip displaying its name, region, and original earthquake count. A custom color legend component, built with reusable D3 selections, appears alongside the map.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4dd1f2510581434a8810ca1aef0b8939?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
