{"version":"1.0","type":"rich","title":"World Map","description":"This example visualizes global population distribution by rendering a world map with cities represented as scaled circles. The map displays land masses, graticules, and country borders, while city markers use a square-root scale to encode population size. The visualization is built with React and D3 v5, using `geoNaturalEarth1` projection via `d3.geoPath` and topojson data from the world-atlas package. Population data comes from a CSV of world cities, with React hooks managing asynchronous data loading.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/40b52eef84c342d4be796d7c200011fc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
