This example uses WebCola to lay out a small directed graph with six labeled nodes and five links, rendering nodes as gray circles with text and links as strokes whose width corresponds to each link’s value. The WebCola `d3adaptor` integrates with d3.v5, applying constraint-based layout with symmetric link lengths and a `start(30)` call. The SVG updates on each `tick` event, while dragging nodes via `d3cola.drag` fixes them in place on click, animating positions in real time.
