{"version":"1.0","type":"rich","title":"Fork of Persons of Concern StreamGraph by Origin","description":"This fork of the Persons of Concern StreamGraph groups cumulative COVID-19 case counts by Chinese province over time. Using d3.stack with the wiggle offset and basis curve, it renders a smooth streamgraph in SVG, with each province as a colored layer. The code interpolates missing daily values between reported dates and applies a unique color to each province. Hovering a layer turns it black for emphasis, while white labels are positioned via d3-area-label. Data is loaded from a local JSON file via d3.json.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ff56035bcb2544a4a8c76e8cd0a73e73?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
