A bundle of new features for NodeXL v.177: Edges++

14SepMay 7, 2015 By Marc Smith

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.

NodeXL (v.174) throws a curve: edges that bend (a bit)

13AugMay 7, 2015 By Marc Smith

Curved edges have arrived in NodeXL (v. 174).

Here is a network visualization with all the edges drawn as straight lines:

The same network graph can be drawn with slightly curved edges:

The result is a slight improvement in readability.

To start, the edges curve just a bit. Soon, we will allow user control over the extent of the curvature.

Turn on curved edges by checking the box in the Graph Options dialog accessed from the graph pane.
