{"version":"1.0","type":"rich","title":"Fork of Fork of Circles on a Map","description":"This visualization displays global population by country with proportional circles, where circle area corresponds to 2018 population data from a CSV file merged with TopoJSON world map geometry. The map uses d3.geoNaturalEarth1 projection and d3.geoPath for rendering, with d3.zoom enabling pan and zoom interaction. Color and size legends built with custom d3 functions show population magnitudes, while hover tooltips reveal country names and exact values. The SVG rendering applies a natural earth projection with semi-transparent teal circles overlaying gray country boundaries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/69b389a684db407f80d82d1f767a933b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
