title: How can one set the size of an igraph plot?
body: <p>I'm currently plotting my graphs like this:</p>
  
  <pre><code>        ig.plot(graph, target=file, vertex_color=membership,
              vertex_label=[index for index, value in enumerate(graph.vs)],
              vertex_frame_width=0,
              palette=ig.ClusterColoringPalette(len(set(membership)) + 3))
  </code></pre>
  
  <p>The plot is output to a PDF file on a single page. It looks decent but the nodes are too crowded. Is there a way to pull the nodes apart so that I can actually see all the edges? I was thinking of increasing the size of the plot but I don't know how to do that.</p>
  
  <p>Here's how it looks right now: <img src="https://i.stack.imgur.com/eYmBl.png" alt="current plot"></p>
