{"version":"1.0","type":"rich","title":"Points on a Map","description":"This example visualizes the global distribution of cities, with circle size encoding each city’s population using a square-root scale. A Natural Earth projection renders landmasses, graticules, and country borders via `d3.geoPath` and `geoNaturalEarth1`, while city points are positioned using the same projection. Data comes from a CSV of world cities and TopoJSON world-atlas geometry, all drawn as SVG within a React component.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/58d862c56a2d4c46b7a208d40eb76d44?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
