{"version":"1.0","type":"rich","title":"Points on a map","description":"This example displays a world map with points representing cities, sized by population. The map is rendered as SVG using React, with D3's `geoNaturalEarth1` projection and `geoPath` drawing landmasses, graticules, and sphere outlines. City coordinates are projected onto the map, and circles are scaled with `scaleSqrt`. The code loads world topology from a JSON via `useWorldAtlas` and city data from a CSV using the `csv` utility, styling land areas and points with CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2c55710e7a7b4c92951c3c65426dff5f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
