title: how to generate img with same spacing
body: <p>I generated a graph from this output:</p>
  
  <pre><code>digraph G {
      { rank = same; 1; 2; 3; 4; 5; 6; 7; 8; 9; };
      2 -&gt; 3 [label="hi there"];
  }
  </code></pre>
  
  <p>However the label is long, which results in the space between nodes 2 and 3 being greater than the space between the other nodes. How can I make it so that the space between all other nodes matches the one between 2 and 3 (that is, the biggest of them all).</p>
