{"version":"1.0","type":"rich","title":"Chloropeth Map","description":"This choropleth map visualizes countries by their economic classification using a red-yellow-green color scale. Built with React and D3, it renders geographic boundaries via the `d3.geoPath` projection on a natural Earth base layer, with country data loaded from TopoJSON and TSV files. A color legend with animated transitions shows the ordinal scale mapping, and the map supports interactive zooming through `d3.zoom` events, while hover states provide tooltips with country names and economic values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6475a4f5f57e4220923004a9db49fe58?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
