{"version":"1.0","type":"rich","title":"Fork of Points on a Map","description":"This example displays a natural Earth projection world map with cities over 50,000 people plotted as small circles. The visualization uses D3 v5’s `geoNaturalEarth1` and `geoPath` for map geometry, with graticules and country borders styled via CSS. City coordinates are projected from latitude and longitude, and React manages the SVG rendering. Mouse hover changes a city’s fill color. Data comes from a Simplemaps world cities CSV, while country boundaries use the World Atlas TopoJSON.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d1220e2f81794ac49855625996d87076?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
