Re: [igraph] Is it possible to use igraph in Java?

I guess rJava works the other way round; i.e., it allows you to access  
Java objects from R.

Do you mean that you want to generate a layout with igraph, save the  
coordinates and then use that to plot something in Processing? That  
should be simple; assuming that g is your graph in Python, you can  
simply do as follows:

from igraph import *

# Construct your graph here

layout = g.layout("kamada_kawai_3d")
f = file("layout.txt", "w")
for x, y, z in layout:
  print >>f, x, y, z
f.close()


You can also construct a Python script that simply writes the  
coordinates to stdout and then call it from Java and read the output  
of the Python script directly.
