{"version":"1.0","type":"rich","title":"Fork of Choropleth Map with Interactive Filtering","description":"This choropleth map visualizes world countries colored by their economic group, with an interactive color legend that filters the map to show only countries in a selected category. Clicking a legend entry dims non-matching countries to 10% opacity while highlighting the selected group, and clicking again resets the view. The visualization uses d3.geoPath with a natural Earth projection, d3.scaleOrdinal with a spectral color scheme, and loads country boundaries and metadata from the world-atlas package. A zoom interaction is also included, allowing users to pan and scale the map.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b4f32e6167f74e039bcdafa7cea8e9bd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
