{"version":"1.0","type":"rich","title":"Fork of Points on a Map","description":"This example displays a world map with cities having populations over 50,000, plotted as semi-transparent teal circles. It uses a natural Earth projection via `geoNaturalEarth1` and renders both graticules and country interiors with `geoPath`. The map is built with React, loading geographic data from World Atlas TopoJSON and city coordinates from a Simplemaps CSV. City positions are projected using `[d.lng, d.lat]` to determine circle placement within an SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f37d88ea26814ea79b8e0172a2074833?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
