{"version":"1.0","type":"rich","title":"Points on a Map","description":"This example renders a world map with city populations using a natural Earth projection. The visualization uses D3’s `geoNaturalEarth1` projection and `geoPath` to draw landmasses, graticules, and country interiors, while scaled circles overlaid onto the map encode each city’s population with a square-root scale. The data comes from the Data Canvas Sense Your City dataset, loaded via `d3.csv`. The React application asynchronously fetches the world atlas and city data, then renders the visualization as an SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/636ec30bd3de4e4493a821ff3ed29511?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
