{"version":"1.0","type":"rich","title":"Points on a Map","description":"A world map displays cities as semi-transparent teal circles, sized proportionally to population using a square-root scale with a maximum radius of 15 pixels. The visualization combines a Natural Earth projection with graticules, land masses, and country borders, rendered via `d3.geoPath` and TopoJSON from the world-atlas dataset. Point positions are calculated using `d3.geoNaturalEarth1`, while city data comes from a CSV loaded with `d3.csv`. React manages the component state, and SVG circles represent each urban center.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ca83e751adea4d44a3caf02d9bfa8a96?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
