{"version":"1.0","type":"rich","title":"Persons of Concern StreamGraph by Origin","description":"This visualization shows the cumulative number of COVID-19 cases across Chinese provinces over time, using a streamgraph where each colored band represents a province's reported case count. The data, sourced from daily JSON records, is interpolated to fill gaps between dates. Built with D3 v4, it uses `d3.stack` with the `stackOffsetWiggle` and `stackOrderInsideOut` methods, alongside `d3.area` with `curveBasis`. Labels are positioned via the `d3-area-label` library, while axes and styling are handled through standard D3 scales and SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4ddd66b9fb074a3e9586c8c028f9f54c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
