This example presents a graph visualization as a series of four interactive demonstrations. It first shows a node-link diagram using a force-directed layout, then compares it to an adjacency matrix representation. The visualization then implements edge-bundling for the node-link diagram and concludes with a slider that allows users to modulate the amount of tension in the edge bundling. The examples use D3.js and are embedded from VizHub, with each part linked to its source code.
