{"version":"1.0","type":"rich","title":"d3 Choropleth Map with Interactive Filtering","description":"This choropleth map displays world countries colored by economic classification, with a legend that filters the map by clicking a category. It uses d3.geoPath with a natural Earth projection to render the countries from a TopoJSON file. The colorLegend component uses d3.scaleOrdinal and schemeSpectral for the color scale, and clicking a legend item reduces the opacity of non-matching countries while highlighting the selected ones.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6f48029b6aa84d1ab0c6b4696394b4ec?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
