{"version":"1.0","type":"rich","title":"Points on a Map","description":"A world map displays country boundaries and graticules, with semi-transparent circles sized by population for major cities. The visualization uses React with D3 v5, employing `geoNaturalEarth1` and `geoPath` for the projection along with `geoGraticule` for grid lines. City data comes from a CSV, while country shapes are loaded from World Atlas TopoJSON. Circle radii are scaled using `scaleSqrt` based on population values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0c82e2f1bd5a495885a98bbf5090d982?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
