{"version":"1.0","type":"rich","title":"Fork of Points on a Map","description":"This visualization displays a world map with cities whose populations exceed 50,000, sourced from the Simplemaps World Cities Database. The map uses a natural Earth projection, rendered as SVG through React, with country boundaries from the World Atlas TopoJSON. D3's `geoNaturalEarth1` projection, `geoPath`, and `geoGraticule` functions draw the sphere, graticules, and landmasses, while city coordinates are projected and plotted as semi-transparent teal circles. The styling employs muted grays for geographic features, creating a clean backdrop for the city data points.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a445d13de1714ca3aa6745bd4f4570d5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
