Hi all,
Can anyone who is willing give my new version of the Circular Layout plugin a test? I've added some features to it that I would really like wider testing (and feedback) on before I release it.

New features which need testing are:

• Sorting by any arbitrary node attribute.
• New "Radial Axis" layout.

The radial axis layout sorts nodes into groups based on an attribute and arranges a circular layout with radial spars (axes) for each group.

For example, here is the Les Miserable dataset grouped by modularity and sorted with degree ascending outward: Another example, here is the power grid dataset sorted the same way: And before anyone assumes it only results in "flowers", here is the Java function dataset grouped by "Strongly Connected ID" and sorted with descending degree outwards: You can download a beta version of the plugin here:

Please let me know any thoughts you might have!

This is a great layout! I haven't had the chance to really try to play with it but I have some ideas. Here's the long-in-the-tooth DH@Stanford Graph made beautiful:



I think it's going to work best if it relies on user-defined attributes for the sorting, as there seem to be too many modularity classes in most graphs. Still, I haven't really had a chance to play with it. One thing I'd like to see, if it's possible, is the integration of a false Z-axis for isometric display, especially if it could render false perspective for the node sizes as a modification of their existing sizes. That sounds like a lot of trouble, but I'm throwing the idea out there.

Thanks, Elijah! I'm glad you find the layout interesting!

I will give your idea of a false Z-axis view of the layout some thought. I think I might wait and see what changes might come in the visualization engine itself before I dig into that too far.

Please let me know if you run into any problems with layout in the mean time. I appreciate you looking at it!

Hi Elijah,
I meant to follow up on your comment:

I think you are absolutely right! I used modularity classes for the two demo graphs mostly because I was being lazy. I think the real strength of the layout will be with user-defined attributes. For example, Sébastien mentioned on the Gephi-plugin mailing list that he had played with a time interval to group the nodes and had found some success.

I honestly haven’t fully explored the ways to use the layout… and I am torn between using my time to add to the Circular Layout plugin or to reparse some of my datasets so that they have more attributes. *grin*

Thanks for testing it and I love the simplicity of the graph you posted above!

Grouping nodes by Timestamp works also very well on dynamical network...

I'd love to see that.

This is my new favorite layout. It's great for showing graph statistics visually.

I have a quick question: I have a network I want to visualise using radial axis; when I group nodes according to degree I get axes but if I sort according to modularity I only get a circular layout and the axes disappear. I want my modules to be sorted as axes. Any idea how I can fix this?
Thanks
