{"version":"1.0","type":"rich","title":"Population worldmap","description":"This worldmap visualization displays global population estimates for 2018, overlaying semi-transparent circles on each country’s centroid, sized by population using a square-root scale. The map supports zooming and panning, with a color legend and size legend for reference. Built with D3 v5, it uses `geoNaturalEarth1` and `geoPath` for the map projection, `geoCentroid` for circle placement, and `zoom` for interactivity. Population data comes from a UN CSV dataset, merged with country geometries from a TopoJSON world atlas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6179157ea56c495091c6f786f5157a97?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
