{"version":"1.0","type":"rich","title":"Points on a Map","description":"A world map rendered with a Natural Earth projection displays global cities as semi-transparent circles, sized by population. The visualization uses React and D3 v7, with `geoNaturalEarth1` and `geoPath` to draw landmasses, graticules, and country interiors from TopoJSON data. City coordinates are projected and plotted as SVG circles, with a sqrt scale mapping population to radius. Data comes from a CSV of world cities loaded via `d3.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6df9d580d03f48858dffd28023466d17?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
