[Biopython] Phylo.draw_graphviz(tree) not showing node names

[Jan Zaucha]

Hi everyone,

I'm trying to visualize the trees I generate, but for some reason the plots
do not display the node names. When I print the tree each node has an
associated name (string format). Phylo.draw(tree) also works fine and plots
a tree with the node names.

I simply use:
Phylo.draw_graphviz(tree)
pylab.show()

There is no error, I can't work out how to force the node names to be
printed.

Any ideas?

Thanks,
Jan Zaucha
