It uses the `d3.pack()` layout algorithm, `d3.hierarchy()` for data structuring, and `d3.schemeCategory10` for color encoding. Interactive tooltips provide details on GDP, population, and CO2 emissions. The code relies on a custom tooltip component and data transforms to organize the hierarchical dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9d52b2ac763246289f9df08b67985400?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
