{"version":"1.0","type":"rich","title":"Choropleth map with interactive filtering","description":"This choropleth map displays countries colored by economic classification, with a linked legend that filters the map to highlight selected categories. Clicking a legend entry dims all other countries and emphasizes those matching the chosen value. The visualization uses d3.geoNaturalEarth1 projection and d3.geoPath to render geographic features from TopoJSON world atlas data, while a d3.scaleOrdinal with a spectral color scheme maps economic groups to colors. Interactive zoom and filtering are implemented via d3.zoom and click handlers on the SVG legend elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/13ea39c999244a9b9a88704c3141ac0d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
