{"version":"1.0","type":"rich","title":"Fork of Points on a Map","description":"This visualization displays over 4,000 cities with populations exceeding 50,000 as semi-transparent points on a natural Earth projection. The map includes geographic context through landmasses, graticules, and country borders. Using React with d3.geoNaturalEarth1 and d3.geoPath, it renders the World Atlas TopoJSON shapes as SVG paths, while city coordinates from the Simplemaps World Cities Database are projected to circles. The code demonstrates asynchronous data loading with d3.json and d3.csv hooks, filtering the initial dataset to only larger urban centers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5a7aa1d88ab14fe997ea8c5ec9fc905c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
