{"version":"1.0","type":"rich","title":"Points on a Map","description":"This example displays a world map with cities sized by population. Natural Earth projection renders landmasses, graticules, and country borders using d3.geoPath. City points from a CSV dataset are projected onto the map and drawn as semi-transparent circles, with radius scaled by population using d3.scaleSqrt. React manages component state and rendering, while d3.v7 handles geographic calculations and data loading.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8a55c86afebb47f48f87bb0167af57b7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
