{"version":"1.0","type":"rich","title":"Fork of Choropleth Map with Interactive Filtering","description":"This choropleth map displays global economic groups, with countries colored by their economy category. Selecting a color in the legend interactively filters the map, highlighting only countries in that group while dimming the others. The visualization uses the `d3.geoPath` and `d3.geoNaturalEarth1` projections for geographic rendering, and `d3.scaleOrdinal` with the spectral scheme for color assignment. Data comes from the world-atlas dataset, loaded via `d3.tsv` and topojson. The map supports zooming through the `d3.zoom` event handler.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/eab8020fb2ef4df0aae05689d8da6f20?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
