{"version":"1.0","type":"rich","title":"Fork of Polished World Map","description":"This map visualization displays global city populations as proportional circles overlaid on a world map with country boundaries, graticules, and interior borders. The map uses a Natural Earth projection, with data sourced from the World Atlas TopoJSON and a clean CSV of world cities. Built with React and D3 v5, the code leverages `d3.geoNaturalEarth1`, `d3.geoPath`, and `d3.geoGraticule` for the geographic elements, while `d3.scaleSqrt` maps population values to circle radii. The SVG rendering is styled with a cohesive gray and teal palette.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6840d586e5ca4feb859cab66c0f05302?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
