Two interactive force-directed graphs render the same ego network side by side, with nodes and edges laid out using the WebCola constraint-based layout library via its D3 adaptor. The visualization encodes nodes as colored circles and links as gray lines, with graph data pulled from a JSON file containing nodes, links, and group hierarchies. A button and spacebar trigger a dynamic animation that disconnects or reconnects all edges from node 0, updating both D3 SVG renderings simultaneously to compare the resulting layout changes.
