Luka Potkonjak has contributed a new feature to NodeXL: edge bundling. Following on the heels of the release of curved edges in version. 175, we now provide a way to gather parallel edges together into “bundles” that travel together until they diverge close to their destinations.
The effect is visually striking. Here is a before and after with the same network:
Curved Edges, no Edge Bundles
Curved and bundled edges.
In future releases we will expose more controls for configuring the bundles.
