{"version":"1.0","type":"rich","title":"Fork of Streamgraph of covid-19","description":"A streamgraph visualizes COVID-19 case counts across five continents from January to December 2020, using a silhouette offset layout. The SVG rendering, built with D3 v2 in a React framework, loads data from CSV files for daily and monthly aggregation. Hovering a layer fades others and displays a tooltip with the region, case value, and date. The implementation relies on D3's `layout.stack`, `svg.area`, and time scale APIs, with color encoding based on a sequential orange palette.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b3966207c63748e5838c78891c3f8000?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
