A custom colorLegend displays ordinal values as circles with labels, and country data comes from TopoJSON world-atlas files joined with tab-separated metadata. Hovering highlights individual countries, and tooltips show each nation’s name and economic group.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f3d8f8b6f6e14f0e8f4ffb99e5ccc257?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
