{"version":"1.0","type":"rich","title":"Fork of Points on a Map","description":"This example shows a world map with over 50,000 cities plotted as semi-transparent points, using a Natural Earth projection. The visualization layers graticules, land masses, and country borders beneath the city data, with each city positioned via the `geoNaturalEarth1` projection and `geoPath`. Built with React and D3 v5, the code loads TopoJSON world atlas data and a CSV of city coordinates, rendering the map as SVG. City data comes from Simplemaps’ World Cities Database.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3a97ad9c23a0451f96c397085773307c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
