This example visualizes a network of laboratory processes, showing the relationships between nodes such as “Softwaresysteme” and “Blutprozessierung.” The nodes and links are rendered as circles and lines in an SVG, with labels displaying each process name. The layout is computed using `d3.forceSimulation` with forces for charge, link distance, centering, and collision, while user interactions allow dragging nodes. Hovering over a node triggers a `transition()` to enlarge it. The data originates from a JavaScript module containing predefined nodes and links.
