{"version":"1.0","type":"rich","title":"Sunkey Test","description":"This example visualizes COVID-19 transmission pathways as a Sankey diagram, showing flows from a central transmission node to categories like public transit, social contacts, and travel-related locations. The diagram uses draggable nodes and links with stroke widths proportional to flow values, with labels indicating percentages. Built with D3 v4, it employs the `d3.sankey` plugin to compute the layout, renders nodes as SVG rectangles, and uses `d3.drag` for interactive repositioning. Data comes from a local JSON file containing nodes and links, with color mapping via `d3.scaleOrdinal`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/097706e735f04549bee2c559413eb734?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
