{"version":"1.0","type":"rich","title":"Using Size","description":"This example displays a world map using Natural Earth data, with city points sized by population. The visualization uses a square-root scale to map population values to circle radii, with a maximum radius of 12 pixels. Built with React and D3 v5, it employs `geoNaturalEarth1` projection, `geoPath` for rendering land and graticules, and the `scaleSqrt` API for size encoding. The map is styled with a light color palette and semi-transparent teal circles, presenting an aesthetically polished geographic view.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/41ce58ffbf9d4cc7b23849ac94e7ea7c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
