{"version":"1.0","type":"rich","title":"My map","description":"This map shows European and North African cities with their populations, plotted as points over country boundaries.

City labels appear beside each point, with styling controlled by the map.css file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ca6d553f80d347e7be345efbcf8d41bb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
