Re: [igraph] vertex shape: triangle

[Gábor Csárdi]

Not very easy, as there is no API for this. You'll need to write code
(1) to plot the triangles, that is easy, and (2) to calculate where
the arrows should be plotted, this is a bit harder, but probably not
very bad. Then you need to unlock some igraph data structures to add
your new shapes.

Here is an example on how to do it:
http://lists.gnu.org/archive/html/igraph-help/2009-09/msg00016.html
This defines the "circle2" shape, which is the same as "circle", but
you can change the frame width.
