{"version":"1.0","type":"rich","title":"Fork of Points on a Map","description":"This visualization displays a world map populated with circles representing cities with populations over 50,000. The map uses a Natural Earth projection with visible graticules, country boundaries, and landmasses rendered in muted grays. City coordinates are projected from longitude and latitude data using D3’s `geoNaturalEarth1` and `geoPath`, with circles drawn as SVG elements. The example is built with React, relies on D3 v5 for data loading and projection, and sources city data from Simplemaps and country boundaries from the World Atlas TopoJSON.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5234748c9d4f4f05a1a79e6b20c3f300?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
