{"version":"1.0","type":"rich","title":"Points on a Map","description":"This example displays a world map with dots marking cities that have populations exceeding 50,000. The map uses a Natural Earth projection and renders land masses, graticules, and country borders as SVG paths. City positions are projected from longitude and latitude coordinates using `d3.geoPath` with `geoNaturalEarth1`, and each city is drawn as a semi-transparent circle. The visualization loads world atlas TopoJSON data and a city CSV dataset, with React managing the component lifecycle.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4a94ec9d1cd348d394e69e9083b86684?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
