Hovering highlights a country in red, and the map includes a legend showing color categories. Built with D3 v5, it uses `geoPath` with the Natural Earth projection and loads geographic data from the world-atlas TopoJSON and TSV files. The visualization supports zooming via D3's zoom event and renders as an SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/260893f9311f4da7bb579b0015f06a43?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
