{"version":"1.0","type":"rich","title":"Map with Selectable Countries","description":"This map visualization displays global economies using a choropleth projection, where each country’s color corresponds to its economic classification from World Atlas data. Users can click individual countries to highlight them and dim all others, with a legend that also supports filtering by economic category. The implementation uses d3.geoPath with a geoNaturalEarth1 projection, d3.zoom for panning, and d3.scaleOrdinal with schemeSpectral for coloring. TopoJSON loads the geographic boundaries, while SVG paths render the interactive map and legend controls.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/360c081e1ad4449ab7f46bb8fa62803f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
