{"version":"1.0","type":"rich","title":"SANKEY Experiment","description":"This interactive Sankey diagram visualizes the flow of values between API endpoints in a Swagger-defined pet store, grouping operations like GET, POST, PUT, and DELETE toward response codes. Built with D3.js v3 and the custom `d3.sankey` layout, nodes are draggable via `d3.behavior.drag`, triggering `sankey.relayout()` to recompute link paths. The SVG rendering uses `sankey.link()` for curved, stroke-width-scaled flows and colors nodes by category. Input data comes from a JSON file mapping resource operations to HTTP methods and status codes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/245b41b5b7504f3a88d2f5b46d006902?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
