{"version":"1.0","type":"rich","title":"Points on world map","description":"This visualization displays world cities as scaled circles on a natural Earth projection, with marker size encoding population using a square-root scale. The map renders land masses, graticules, and country borders in muted grays, while semi-transparent teal points overlay major urban centers. Built with React and D3 v7, it uses `geoNaturalEarth1` with `geoPath` for geographic projection, TopoJSON for world atlas data, and `scaleSqrt` to map population values to circle radii. City coordinates and populations come from a CSV dataset loaded via D3’s `csv` function.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c404d73aee954ddba935592aa0b39610?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
