{"version":"1.0","type":"rich","title":"Circle on the Map3","description":"A world map displays population changes by country from 2020 to 2030 using animated, scaled circles. D3's `geoNaturalEarth1` projection and `geoPath` render the landmasses, while `transition().delay()` sequentially animates each country circle's radius to reflect yearly population estimates from a CSV file. A legend using `scaleSqrt` and `sizeLegend` explains the circle-size mapping, and hovering highlights individual countries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4f38cbf87fd34d7085eab284f013d8bd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
