{"version":"1.0","type":"rich","title":"Persons of Concern StreamGraph by Origin","description":"A streamgraph shows the number of COVID-19 cases across Chinese provinces over time. The visualization uses D3.js v4 with a stacked area chart, employing `d3.stack` with `stackOffsetWiggle` and `stackOrderInsideOut` to create the flowing shape. Data is interpolated between recorded dates using a custom bisector function. Labels are positioned with the `d3-area-label` library, and the chart renders as an SVG with hover interactions that highlight individual provinces. The underlying data comes from a JSON file tracking daily case counts per region.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bbd6c3effa4241818aca7358f76f92a9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
