{"version":"1.0","type":"rich","title":"React world map + population points","description":"This example visualizes global population distribution by overlaying cities as scaled points on a world map. The map is rendered using SVG paths from TopoJSON land and country border data, with a graticule for geographic context. City population values are mapped to point radii using a square-root scale from d3, with each city positioned via the geoNaturalEarth1 projection. The visualization is built with React, fetching data from world-atlas and a curated World Cities CSV, and populating the map once both datasets load.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e8552e0e94614048b274a12e854c184e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
