The visualization supports zooming and panning through d3.zoom, with country names and income groups revealed via tooltips on hover. Built with d3.geoPath and geoNames from the world-atlas TopoJSON dataset, it renders as SVG paths over a blue sphere. A custom color legend component displays the ordinal scale’s domain, while hover interactions highlight individual countries in red.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7b4477f87d18482fa4a6c9daff4160df?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
