{"version":"1.0","type":"rich","title":"Sized Points on map","description":"This example displays a world map with cities represented as sized points, where the radius of each circle corresponds to the city's population. The visualization uses a natural Earth projection, rendered via SVG in a React application, with the `d3.geoNaturalEarth1` projection and `d3.geoPath` for geographic boundaries. Graticules and land interiors are styled with subtle gray strokes, while city circles are drawn using `projection([d.lng, d.lat])` and scaled with `d3.scaleSqrt`. Data comes from a CSV of world cities and the World Atlas TopoJSON.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6adce910af324211b9d1c5e25d7d14a1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
