{"version":"1.0","type":"rich","title":"Points on a Map","description":"A world map displays cities with population over 50,000 as semi-transparent teal dots, projected using the Natural Earth projection. The visualization layers graticules, land masses, and country borders from World Atlas TopoJSON, with city coordinates from a Simplemaps CSV. React manages the component state while D3’s `geoNaturalEarth1`, `geoPath`, and `geoGraticule` handle the geographic rendering, and `csv` and `json` load the external datasets.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4d82c23eee4b44febb24ac548789d0ef?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
