{"version":"1.0","type":"rich","title":"SANKEY Diagram for Spread of COVID-19","description":"This Sankey diagram visualizes the early spread of COVID-19 between countries, with China as the primary source and the USA as the main destination, using weighted links to show transmission flow. The D3 v5 code loads data from a JSON file and renders an interactive SVG using `d3.sankey()` for node alignment and link path generation. Nodes are draggable via `d3.drag()`, and link thickness reflects transmission values, with colors assigned using `d3.scaleOrdinal`. The layout computes node positions through iterative relaxation and collision resolution.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/60ab52f1171940f69148a9fc39de7b3d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
