{"version":"1.0","type":"rich","title":"Points On A Map","description":"This example plots thousands of world cities as a cloud of semi-transparent points on an interactive SVG map. Using a stereographic projection, D3’s geoPath renders the sphere, graticule, landmasses, and country borders, while circle elements position each city according to its latitude and longitude. The city data comes from a clean CSV sourced via simplemaps.com. React components manage data fetching with hooks, and D3’s csv and topojson helpers load and parse the datasets.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0e390d23d06f4ed19ae3ba0637302dc1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
