{"version":"1.0","type":"rich","title":"Centered US Choropleths Map","description":"A choropleth map of US states displays state-level rates using a green color scale, with state boundaries from the US Atlas TopoJSON and state rate data from a TSV file. The visualization uses React with D3’s `geoAlbers` projection and `geoPath` to render SVG paths, applying a `d3.scaleThreshold` color lookup based on each state’s rate. The map includes a sphere background and interior state borders, with loading handled via `Promise.all` to fetch both TopoJSON and TSV data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d3019ab9349a4c7b9225a206557df301?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
