{"version":"1.0","type":"rich","title":"Points on a Map","description":"A world map displays over 50,000 cities as translucent teal dots, with country boundaries and graticules rendered in soft gray. The visualization uses React to manage component state and D3 v5's `geoNaturalEarth1` projection and `geoPath` to convert geographic coordinates into SVG paths. City locations are projected from latitude and longitude into screen positions, while the world atlas TopoJSON is processed with `feature` and `mesh` for land and interior borders. Data comes from a Simplemaps CSV containing city populations.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8555d77578734f44963d87fe564253a5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
