{"version":"1.0","type":"rich","title":"Sized Points on a Map","description":"A world map displays cities with populations over 50,000 as semi-transparent teal circles, with point size scaled by population using a square-root scale. The map renders SVG paths via `d3.geoPath` with a natural Earth projection, including graticules, land masses, and country interiors from TopoJSON world-atlas data. City coordinates are projected from latitude and longitude, with React components managing the visualization and D3 modules handling data loading and scales.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5bbfb74ab7b44977a3d9672e3e8ed5ca?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
