{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map colors countries by economic classification using a sequential yellow-orange color scale from the World Atlas TopoJSON dataset. The view uses a natural Earth projection, renders as SVG, and includes pan and zoom via d3.zoom. A custom color legend displays the ordinal scale, while hovering highlights each country with a tooltip showing its name and economy value. The implementation combines d3.geoPath, topojson.feature, and a reusable colorLegend module.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cfea1e5731644e77b3142f6b2831d07f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
