{"version":"1.0","type":"rich","title":"Points on Map","description":"This visualization displays a natural Earth map with circles representing global cities, where each circle’s radius is scaled by population using a square root scale. The map is rendered as SVG through React, using d3.geoNaturalEarth1 for projection and d3.geoPath for drawing land, graticules, and country borders. City data comes from a CSV of world cities, while the map topology is loaded from world-atlas TopoJSON.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3a2733185a694bf7a4a8ee17a5f90055?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
