{"version":"1.0","type":"rich","title":"World Map with Data Points","description":"This visualization displays world city population data as scaled circles on a natural Earth projection. The React app combines D3’s `geoNaturalEarth1` projection, `geoPath`, and `geoGraticule` to render landmasses, country interiors, and graticules, while `scaleSqrt` maps population values to circle radii. Data comes from a preprocessed world cities CSV, with city coordinates projected via D3’s `projection` function to position each semi-transparent point.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cc17b9b5a0e14e3a9b54d679cd0c732d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
