{"version":"1.0","type":"rich","title":"Circles on a Map","description":"This visualization displays global population data for the year 2018, using sized circles positioned on a natural Earth projection map. Countries are colored green or red to indicate whether they have available data. The circles are scaled using `scaleSqrt()` to map population values to radii. The code uses `geoPath` with `geoNaturalEarth1()` for the map projection, and loads data from a CSV file merged with TopoJSON world atlas features.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5084689d9b484cbab1f2ba730e495d3c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
