The area of each circle is proportional to the country’s population, using a square-root scale. Users can pan and zoom the map, and hover over a country to see its name and population, or “Missing data” if unavailable. The map is rendered with SVG using D3 v5, leveraging `geoPath` and `geoNaturalEarth1` for the projection, with data from the UN and a world atlas TopoJSON.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8520917671b24be0b126dd83b7839a46?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
