graph-tool output not working

Hi,

I'm using graph-tool from docker on windows 10 education, and can't draw or
save a graph. Can't figure out why. Posted this on stack overflow
<https://stackoverflow.com/questions/56201514/after-generating-a-random-graph-with-graph-tool-it-doesnt-show-the-graph-and-ca&gt;
but didn't get any suggestions there. Hope someone here can help me solve
this issue.
