{"version":"1.0","type":"rich","title":"world ma Points on a Map","description":"This visualization displays a world map with points marking cities whose population exceeds 50,000, sourced from the Simplemaps World Cities Database. It uses a Natural Earth projection via d3.geoNaturalEarth1 and d3.geoPath to render land, graticules, interiors, and a sphere outline from World Atlas TopoJSON data. City points are projected and drawn as semi-transparent circles. The React-based implementation, using d3.v5 and SVG rendering, creates a clean, minimal aesthetic with light gray landmasses and teal city markers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cda58a20cdb043cfb2c377236e04cf8b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
