{"version":"1.0","type":"rich","title":"Fork of Choropleth Map with Interactive Filtering","description":"This choropleth map visualizes countries colored by economy category using a natural Earth projection. Users can click legend items to filter the map, highlighting matching countries while dimming all others, and can also zoom and pan the SVG view. The visualization uses d3.geoNaturalEarth1, d3.geoPath, and d3.zoom for map rendering, with a d3.scaleOrdinal and schemeSpectral for color encoding. It loads geographic and metadata from the World Atlas TopoJSON and TSV datasets, while the color legend enables interactive filtering through click handlers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/58a7eedfc2394b4ea1b6c1921b9c0cfb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
