{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"This choropleth map colors countries by economy type using an ordinal color scale with a spectral scheme, drawing geographic features with d3.geoPath and a Natural Earth projection. Users can click legend items to filter the map, which dims non-selected countries and highlights the chosen category. The visualization loads world topology from TopoJSON and tab-separated metadata, and implements zooming via d3.zoom. Interactive legend and map updates are managed through D3 v5 selection methods, with hover effects on countries and click-to-toggle filtering on legend ticks.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6cd4139c0a304be981500c5570963150?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
