"Wirkungsketten" visualizes a directed network of interrelated business processes as a force-directed graph. It shows 17 nodes representing process steps, such as "Softwaresysteme" and "Blutprozessierung", connected by 35 links that suggest causal or dependency relationships. The graph is rendered as SVG circles and lines, with node positions computed by d3.forceSimulation using forceManyBody, forceLink, and forceCenter. Node IDs are used as link references, enabling the simulation to dynamically lay out the network within a 960x500 viewport.
