{"version":"1.0","type":"rich","title":"Interactive","description":"A world choropleth map colors countries by economic classification, using a spectral ordinal color scale. Users can click any country to highlight it and dim all others, or click again to clear the selection; clicking legend swatches filters the map to a specific category. The visualization uses d3.geoNaturalEarth1 with d3.geoPath to render TopoJSON country outlines from the world-atlas dataset, d3.scaleOrdinal for coloring, and d3.zoom for panning and scaling. An SVG legend, built with custom functions, adds interactive filtering and selection feedback.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c30f2980f3d843a1be45c7e7a312d718?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
