{"version":"1.0","type":"rich","title":"Points on a World Map","description":"This example displays global population distribution by plotting cities as semi-transparent circles on a natural Earth projection, with circle size scaled by population using a square-root scale. The visualization uses React for component structure, D3 v7’s `geoNaturalEarth1` and `geoPath` for map rendering, and TopoJSON to load world country boundaries. City coordinates and populations come from a CSV dataset, projected onto the map with `projection([lng, lat])`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/98bd1b4bc82e4ff995e63758d40b2013?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
