{"version":"1.0","type":"rich","title":"Fork of Points on a Map","description":"This visualization displays a world map with cities having populations greater than 50,000, plotted as semi-transparent teal circles. The map uses geographic projections from `d3.geoNaturalEarth1` and renders country boundaries, graticules, and land masses using `d3.geoPath`. Built with React and D3 v5, the code loads TopoJSON world atlas data from `world-atlas@2.0.2` and city coordinates from Simplemaps, with topojson’s `feature` and `mesh` functions preparing geographic features for SVG display.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fcbd6f60cff64fbdafd0abdffc715b25?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
