This fork of a SANKEY experiment visualizes the flow of notifications into matched and scrap categories, with further breakdowns into XRM, Prodc, PN OTD, and CRB. The diagram uses a custom `d3.sankey` layout function to compute node positions and link paths, rendering with SVG via D3’s selection and path APIs. Node and link styling is defined through CSS classes, including hover effects on links. Data comes from a JSON file specifying nodes and weighted links, and interactions like dragging are enabled on node rectangles.
