Hi, I've been trying to get this to work for a few hours but I just can't see what's wrong. When outputting as anything but plaintext, arrows in both directions seem to result in only the end arrow appearing. I've tried: [ a ] <--> [ b ] Which results in: +---+ +---+ | a | <--> | b | +---+ +---+ But if I use the --png switch I get a graphic which looks like: +---+ +---+ | a |----->| b | +---+ +---+ Trying with --as_dot outputs: digraph GRAPH_0 { // Generated by Graph::Easy 0.76 at Mon Sep 26 14:50:23 2016 edge [ arrowhead=open ]; graph [ rankdir=LR ]; node [ fillcolor=white, fontsize=11, shape=box, style=filled ]; a -> b [ arrowhead=open, arrowtail=open, color="#000000" ] } ...which also looks like it's only an arrow at the end, not at the beginning. I've tried this on both v0.75 and v0.76 on Ubuntu 16.04.1 LTS. Any ideas? Cheers, Tudor.

Hello Tudor, I recently noticed the same issue, it seems to be a bug in the graphviz output. https://stackoverflow.com/questions/3462433/dot-graph-language-how-to-make-bidirectional-edges The attribute "dir=both" is missing. At the moment I don't have time to work on Graph::Easy, but maybe you can produce a patch? Best regards, Tels
