This visualization uses a D3.js Sankey diagram to show the flow of notification volumes through processing stages. It tracks 65,205 total notifications, which split into matched and scrap categories, with matched items further distributed across XRM, Prodc, PN OTD, and CRB destinations. The SVG rendering uses D3's custom `d3.sankey` layout API, which computes node positions and link depths through iterative relaxation. The diagram employs curved paths for links and semi-transparent black strokes, with nodes rendered as draggable rectangles.
