I am not 100% sure on this but I think as of now its not possible without
writing your own graph actor or something.

But probably what you can do is  use the edge weight array for coloring the
edges and select a vtkLookupTable with alpha ranging from 0 .0 - 1.0 (or
pick what suites your data best).

hope that helps.
