{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"A choropleth map of world countries, colored by ordinal income group, includes a color legend that filters the map when clicked. Clicking a legend label dims all countries except those in that group; clicking the same label again clears the filter. The map uses the `geoNaturalEarth1` projection with SVG paths generated by `geoPath`, and the legend re-renders via an `onClick` handler. Data is loaded from a world-atlas TopoJSON and TSV files.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f5befee2fb2d4b92bfae7dfbf882c12e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
