{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"This choropleth map displays world economies by color, with an interactive legend that filters countries by economic category. Clicking a legend item dims non-matching countries while highlighting the selected group. The visualization uses d3.geoNaturalEarth1 projection with d3.geoPath to render TopoJSON data from the world-atlas package, while d3.scaleOrdinal with schemeSpectral assigns colors. Zoom and pan are enabled via d3.zoom, and clicking legend items toggles opacity and stroke styling through SVG attributes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d91d37b2a5154c5fb55f5d118c03c6b5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
