{"version":"1.0","type":"rich","title":"NEW MAP","description":"This map visualizes the distribution of world cities by population, using circle size to represent each city's population value. The visualization employs D3's geoNaturalEarth1 projection and geoPath to render landmasses, a graticule, and the sphere, with geoGraticule generating the grid lines. Cities are positioned using the projection, and their radii are scaled using d3.scaleSqrt, ranging up to 15 pixels. The React-based application loads geographic data from the world-atlas package and city data from a CSV file containing population figures.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ff291b6e163f420d80ebb4c4616cfd2c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
