{"version":"1.0","type":"rich","title":"Circles on a map!","description":"This map visualization displays the world's population in 2020 using a Natural Earth projection. Each country is drawn as a shaded geographic region, with a semi-transparent circle centered on its centroid, where the circle's area is proportional to the population. Countries missing data are highlighted in pink. The visualization is built with D3.js, using `d3.geoPath` for map rendering, `d3.geoNaturalEarth1` for projection, and `d3.scaleSqrt` for the circle size scale, with data loaded from CSV and TopoJSON files.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/18ad42a87d18420c947a928197e8e5f7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
