{"version":"1.0","type":"rich","title":"Points on a Map","description":"This interactive map displays over 7,000 cities as semi-transparent teal points, overlaid on a neutral world map with graticules and landmasses drawn using D3’s `geoNaturalEarth1` projection and `geoPath`. City locations come from the simplemaps World Cities Database, filtered to populations above 50,000, and are projected using `d3.geoPath` from a TopoJSON world atlas. The React app loads data asynchronously via custom hooks, rendering the SVG scene with D3’s `geoGraticule` for the coordinate grid and a sphere outline for context.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/120e16cc66734ad89b1e218dbe144292?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
