Hi Anne,
I've just added a Roassal plugin with the GraphViz-based layout.
Note that I had to hack it to work with RTMultiLine (it was originally designed for different lines which are currently not part of Roassal), so it's possible there will be some issues.
You can load it (if you have latest Roassal installed) via the Roassal plugin menu, or by executing the following
Metacello new baseline: 'GraphVizLayout'; repository: 'github://peteruhnak/graphviz-layout:master/repository'; load
Then look at the class-side examples in RTGraphVizLayout.
Finally if you use this, you shouldn't move elements within the layout (because graphviz layout hard-codes the pathing)… we could probably change this in the future, but I am not sure how (ideally the layout would have to be recomputed, but that's expensive to do live),
So to summarize: * you must have GraphViz installed in your system * you must use RTMultiLine for lines (because only they support bending)
Let me know how it goes,
Peter

Oh, I missed this one :). So, now I can refactor the code that is still using the RTEdge class side methods :).
Great!
Thanks, Doru

Oh, but this has been in Roassal for many months (I have implemented
since right after ESUG). You need to use #source:connectFrom:toAll:
Here is an example that randomly generate a graph and render it using
this facility:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= nbOfNodes := 40. nbOfRandomEdges := 40.
nodes := 1 to: nbOfNodes. edges := (1 to: nbOfRandomEdges) collect: [ :notUsed | nodes atRandom ->
{nodes atRandom . nodes atRandom} ].
b := RTMondrian new.
b shape circle color: (Color black alpha: 0.5). b nodes: nodes.
b shape line color: (Color gray alpha: 0.3). b edges source: edges connectFrom: #key toAll: #value.
b layout force. b -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

Hi,
We discussed this before. Try to draw a hierarchy using classes and
inheritance objects (so, without using the class to superclass navigation). Something like this:
view := RTMondrian new. view nodes: classes. view edges objects: inheritances; connectFrom: #superclass to:
#subclass.
view layout tree. view
It won’t work.
Cheers, Doru

Do you have an example? I am not sure to understand.

This is very cool. We will all benefit from this documentation.
One thing that I would still like to see fixed before the release is
the edge building (this problem of not being able to properly specify random objects to be taken into account when building edges). Could we work on that?
Cheers, Doru

Dear community,
As you may have seen, Roassal has entered a stabilization phase. The
book AgileVisualization.com will soon be released. After its release, Roassal will go over a new development phase. In order to prepare it, I am asking this question:
What are the 3 aspects you would like to see improved in Roassal?
