The visualization renders geographic boundaries with d3.geoPath and a natural Earth projection, with zooming enabled via d3.zoom. Hover effects highlight individual countries, and a custom color legend built with SVG circles and text explains the color categories. Country names and economic data are loaded from TopoJSON and TSV files using d3.json and d3.tsv.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2bb5757ede514243a68f4df12830fc95?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
