{"version":"1.0","type":"rich","title":"Points on a map","description":"This visualization displays world cities as points on a natural Earth projection, with point size mapped to population via a square-root scale. The map renders landmasses, graticules, and country interiors using `d3.geoPath` from the `d3` library. City data is loaded as a CSV, while world topology comes from the `world-atlas` package, with React managing the application state and SVG rendering. Hovering over a city reveals a tooltip with its name, country, and population.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3fd8093caa01435280496e29d6598fd4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
