can't use networkx.read_dot()
When trying the following
import networkx networkx.read_dot("foo.dot")
ImportError Traceback (most recent call last) /home/bla/tmp/<ipython console> in <module>() /local/usr/share/sage/local/lib/python/networkx/drawing/nx_agraph.pyc in read_dot(path) 197 except ImportError: 198 raise ImportError, \ --> 199 "read_dot() requires pygraphviz: http://networkx.lanl.gov/pygraphviz" 200 A=pygraphviz.AGraph(file=path) 201 return from_agraph(A) ImportError: read_dot() requires pygraphviz: http://networkx.lanl.gov/pygraphviz
It seems that I'm missing something really simple here. After a fair time browsing the documentation, however, I couldn't find what :(
Thanks in advance.
