{"version":"1.0","type":"rich","title":"Sized Points on a Map","description":"This visualization displays a world map with cities of populations exceeding 50,000, using circle size to represent population magnitude. The map is rendered with D3.js, using `d3.geoPath` for country boundaries and graticules from TopoJSON data, while city points are projected and scaled based on the Simplemaps database. The visualization is polished with a Poppins font and a clean, minimal aesthetic, presenting global population distribution at a glance.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/08acb8e735e841a4a1379d30d3919529?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
