I am using GraphStream, to generate some graphs.
I have following questions:
When I use auto-layout in the library, is it possible for me to obtain the position information of each node?
Can I change the type of edge? e.g. the default edge type is solid line. Can I change edge into dash line, or other type?
Thanks.
For the first question I would advise you check the GraphStream website and especially the FAQ on the subject.
For the second question, see the visualisation tutorial as well as the complete CSS reference.
