The map uses d3.geoPath with a Natural Earth projection, rendering TopoJSON data from the World Atlas, and d3.scaleOrdinal with schemeSpectral assigns colors. Hover styling also highlights individual countries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fa7b57c39c1d48fda80cb2cc9260e28a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
