{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"A choropleth map colored by economy type uses an ordinal color scale and a Natural Earth projection to display global income groups. Users hover over legend items to filter the map, dimming non-selected countries and highlighting matches. Built with D3 v5, it combines `d3.geoPath`, `d3.geoNaturalEarth1`, and `d3.zoom` for panning, while the legend uses `d3.scaleOrdinal` and `schemeSpectral`. Data comes from the World Atlas TopoJSON and TSV files rendered as SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0d6db6960d45484fbb90d6e4345e23fd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
