{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"This choropleth map displays global economic classifications by country, with an interactive legend that filters the map to highlight a selected category while dimming others. The visualization uses a natural Earth projection via `d3.geoNaturalEarth1` and renders country paths with `d3.geoPath` in an SVG. Users can click legend circles to toggle filtering, and a zoom behavior (`d3.zoom`) enables panning and scaling. Data comes from the World Atlas TopoJSON and TSV files, with colors mapped using `d3.scaleOrdinal` and `schemeSpectral`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c2243f6cc4c247b7986e78283f56f69b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
