{"version":"1.0","type":"rich","title":"Fork of SANKEY Diagram for Spread of COVID-19","description":"This Sankey diagram visualizes the spread of COVID-19 between countries during the early outbreak, showing primary flows from China to nations worldwide and secondary transmissions between other regions. The D3.js v5 visualization uses the `d3.sankey` layout to render an SVG graph with draggable nodes and curved links. Link stroke width encodes transmission value, while node colors categorize countries using `d3.scaleOrdinal` with the `schemeCategory10` palette. The data originates from a JSON file listing source-target pairs with numeric spread values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ccdd83afa69248fc9e9a8737e61ad297?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
