{"version":"1.0","type":"rich","title":"Points on a Map","description":"Global city populations are visualized as semi-transparent points on a natural Earth projection, with point size encoding population via a square-root scale and a maximum radius of 15 pixels. The map includes graticules, country borders, and landmasses rendered using `d3.geoPath` and world-atlas TopoJSON data. City coordinates and populations come from a CSV loaded with `d3.csv`, while the React application uses hooks to fetch and render the visualization with SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e5360c60b0da42a597e04da6ebf7a4a1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
