DOT Layout

[Ovidiu Serban <ovidiu.serban AT insa-rouen.fr>]

Hi Graph Stream Team,

I have two very short questions:

1.Does it exist in graphStream something similar to dot layout from graphViz ? What I want is a hierarchical static layouting ...
2. Is it possible to define sub-graphs/clusters and draw them in groups ? Dot-like: http://www.graphviz.org/Gallery/directed/cluster.png

I did not find this in the documentation, so this is why I'm asking ...

Regards,
Ovidiu
