<br/>&gt; But this is correct. Does it really take five hours if you supply pos =

<br/>The one that took 6 hours was without supplying &quot;pos&quot;. When I supplied a
<br/>random one, it took more than 2 hours and I stopped it.
<br/>Strangely, unlike the former it uses only one CPU. I believe graph_draw
<br/>is taking too long, because random_layout finishes almost immediatly.
<br/><br/>When using your code to filter the largest component it takes 5 minutes,
<br/>most of the time processing the layout (as shown with the verbose option
<br/>you suggested).
<br/>But graph_draw is not wasting time calculating the graph layout when
<br/>supplied random positions, I don't know what it could be doing.
<br/><br/>Does it also happen to you:
<br/>&nbsp; &nbsp; pos = gt.random_layout(polysemy)
<br/>&nbsp; &nbsp; print &quot;here&quot;
<br/>&nbsp; &nbsp; gt.graph_draw(polysemy, pos=pos, output='ejercicio_5_gv.png')
<br/><div class='shrinkable-quote'><div class='shrinkable-quote'><br/>&gt; &gt; Also I would like to see nodes expanded through the canvas, because
<br/>&gt; they are
<br/>&gt; &gt; densely packed into a corner. What is the option for controlling this?
<br/>&gt;
<br/>&gt; The bounding box is calculated automatically if fit_view=True. If you
<br/>&gt; set it False, the positions will be considered to correspond to the
<br/>&gt; output format units (pixels in case of png, points in case of pdf, etc).
<br/>&gt;
<br/>&gt; If you are getting strange-looking results with fit_view=True, then
<br/>&gt; please send me an example.
</div>I've attached a screenshot, which shows unused space in the image.

<br/>visible, or strech them to fit the picture at least.
