Navigate: links (arrows) don't show

First I thought that something was wrong with my installation, but then I opened the demo (which is 2.1 dev0) and it was the same there.

Am I missing something in my browser? I have tried latest Firefox / Chrome / Edge.

I run version 2.0.1 on an Ubuntu LTS 16.04.

    I think I actually solved this :-)

    It seems like pygraphviz (1.3.1) generates an extra object level when generating the svg for the arrows. Or maybe it is the xml.etree.cElementTree (python-2.7) that does it. Anyway, the remedy was to add another loop level in " (see diff below).
