A color legend built with `d3.scaleOrdinal` and `schemeSpectral` maps each income group to a distinct hue, while hovering highlights a country in red. The map supports zooming and panning via `d3.zoom`. Data comes from the World Atlas TopoJSON and TSV files, rendered as SVG paths with `d3.geoPath`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3be544431f254639a72ed7678e103f70?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
