title: How do you center a title for a diagram output to SVG using dot?
body: <p>So far I tried this line but dot keeps pushing it aside making room for my nodes (pushes it to the right):</p>
  
  <pre><code>_diagram_info [shape="plaintext", label="My Diagram\l", fontsize=13]
  </code></pre>
  
  <p>Is there a way to center the label by pos, using dot?</p>
