Data is fetched from the CSSE COVID-19 time series CSV via `d3.csv`, while the margin convention is applied by translating the main group.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/005f3eccb14d49feb0fbee3bd1c4138a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
