Hi,

after having had some trouble with the installation, I could finally test 
Tulip. My graph is fairly small at the moment, with about 10k nodes and 20k 
edges. I'll have to test if it would work in cytoscape, but I doubt it. In 
that sense, I really like Tulip because it behaves nicely and I can imagine 
that it will do this also for larger graphs. Although, I don't know how large 
they really can get.
What kind of disappointed me are the layout algorithms in Tulip. Even though 
there might be some plugin-layouts which I haven't tested, this is really 
nicely working in cytoscape. Installing e.g. the HistogramView-plugin failed 
due to not understandable reasons.
In total, I would say that Tulip is not really helpful in my case, sadly.

Therefore, I hope that some of you may have other solutions or suggestions to 
the problem.

Best,

Cedric
