{"version":"1.0","type":"rich","title":"Choropleth Map","description":"A choropleth map colors countries by their economy classification using an ordinal color scale with a spectral scheme. The visualization loads geographic data from the World Atlas TopoJSON and TSV files, projecting it with d3.geoNaturalEarth1 and rendering paths via d3.geoPath. Hovering highlights a country in red, while a custom color legend component displays the categorical ranges. Zooming is enabled through d3.zoom, and the map includes a static sphere background.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5e33f34197be42b2bf39bf837dd44bba?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
