{"version":"1.0","type":"rich","title":"Sized Points on a Map","description":"This visualization displays a world map with circles sized by city population, using a square-root scale to encode magnitude. The map includes landmasses, graticules, and country interiors rendered via d3.geoPath and a geoNaturalEarth1 projection. City coordinates and population data come from a CSV dataset, with React managing the component lifecycle and d3.v5 handling data loading and scaling. Semi-transparent teal circles are positioned using the projection and scaled up to a maximum radius of 15 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9a28aac2a07a4a7c8f6a94339a5069d3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
