title: Visualization of GraphML graph?
body: <p>What are the best options to visualize a graph defined in GraphML on Mac OSX or Linux ? R + iGraph seems to be a valid solution according to <a href="https://groups.google.com/forum/#!topic/gremlin-users/SCveZqQcg5I" rel="noreferrer">gremlin-users group</a> but I'm wondering if there is any easier solution, ideally a simple "graphml2png" command line application. Any idea ?</p>
