The diagram shows flow from Chinese provinces to other global destinations, with multiple stages of transmission. It uses D3.js v5 with the `d3.sankey` layout on an SVG canvas. Nodes are draggable, and links are colored and sized by flow value. The visualization draws on JSON data containing numeric link values that represent the rate of spread.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b95d5eb82e4947489b32db149526dda4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
