{"version":"1.0","type":"rich","title":"Fork of Choropleth Map with Interactive Filtering","description":"This choropleth map visually encodes countries by economy group using a spectral color scale. Hovering over legend items interactively filters the map, dimming countries outside the selected category while highlighting the chosen group. The visualization uses `d3.geoPath` and `geoNaturalEarth1` for map projections. Data is loaded from the world-atlas TopoJSON and TSV sources, with legend interactions managed through D3 selections and event handlers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/021d0c6cf4ac44098a66d1052bcd18c3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
