{"version":"1.0","type":"rich","title":"Fork of Sized Points on a Map","description":"This example displays a world map with cities over 50,000 in population, represented by semi-transparent circles scaled by population using a sqrt scale. It uses React for component structure and d3’s geoNaturalEarth1 projection, geoPath, and geoGraticule to render land, country interiors, and graticule lines from World Atlas TopoJSON data. City coordinates and populations come from a CSV loaded via d3.csv, with circle radii capped at 15 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a020836ff8f847268bab3b39be7b3011?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
