{"version":"1.0","type":"rich","title":"Points on a Map","description":"This example visualizes global population distribution by plotting circular marks for cities on a natural Earth projection. The city points are colored yellow with partial transparency, overlaid on a light gray landmass with graticules and country borders. Built with React and D3 v7, it uses `geoNaturalEarth1` and `geoPath` for the map, a square root scale to map population to circle radius, and loads world atlas TopoJSON and city CSV data via `useWorldAtlas` and `useCities` hooks.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/50311236c9fd4dfcb144f9f41a33504b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
