{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"This choropleth map colors countries by economic classification using a spectral color scale. Users can click on legend items to filter the map, which dims non-matching countries and highlights the selected category. The visualization uses d3.geoPath with a geoNaturalEarth1 projection to render world map features from a 50m TopoJSON dataset, while the color legend (built with d3.scaleOrdinal and schemeSpectral) supports interactive click-based filtering. Hovering over a country displays its name and economic value via SVG title elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/adb4e9e1df944b8698a5ed21198bbebd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
