Users can pan and zoom the map using mouse or touch gestures, and hovering over a country highlights it and reveals its name and economic group via a tooltip. The visualization uses d3.geoNaturalEarth1 for projection, d3.geoPath for rendering GeoJSON features, and d3.zoom for interaction. d3.scaleOrdinal with schemeSpectral maps economic categories to colors, while the legend is custom-built from SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/861ba7abd51b42f2884f9abedeafaee6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
