{"version":"1.0","type":"rich","title":"Points on a Map","description":"This example displays a world map with dots marking cities, sized proportionally to population via a square-root scale. The map uses a Natural Earth projection and includes graticules and country borders. The visualization is built with React and D3 v5, leveraging `geoNaturalEarth1`, `geoPath`, and `geoGraticule` for geographic rendering, while city data comes from the Data Canvas Sense Your City dataset. Circles are positioned using the projection and styled with opacity.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/35dc4e2ee1084bc0a3616c7424b4cf8b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
