{"version":"1.0","type":"rich","title":"Persons of Concern StreamGraph by Origin","description":"This streamgraph visualizes the number of confirmed COVID-19 cases in China’s provinces and autonomous regions over time, using a wiggle-offset stacked area chart. Data is loaded from a local JSON file, interpolated for daily values, and rendered as SVG paths using the D3.js stack, area, and curveBasis APIs, with labels positioned by the d3-area-label library. The visualization highlights the rise and fall of case counts across regions, with each colored band representing a province’s contribution to the total.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/80fb218e103c4436a9de798d509c78e0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
