{"version":"1.0","type":"rich","title":"Size by population","description":"This map uses a power scale to scale each country’s area by its projected 2050 population, with SVG paths transformed around their geographic centroids. D3’s `geoNaturalEarth1` projection and `geoPath` draw the world, while `scalePow` and `scaleSqrt` determine the sizing. A hover tooltip reveals the country name and population, and a legend shows the color scale for data values. Population data comes from a UN CSV file, and countries missing 2050 data are rendered white with a “Missing data” tooltip.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d5f233c1e0444745a4782c97db6c3b99?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
