title: How can I make a circular graph in Graphviz?
body: <p>I have this following graph in graphviz:</p>
  <p><a href="https://i.stack.imgur.com/C6LmX.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/C6LmX.png" alt="enter image description here" /></a></p>
  <p>That is generated from this code:</p>
  <pre><code>digraph finite_state_machine {
      rankdir=TB;
      node [shape = none]; Start;
      node [shape = circle];
      nodesep=.5;
      Start -&gt; A;
      
      A-&gt;B
      B-&gt;C
      C-&gt;D
      D-&gt;E
      E-&gt;F
      F-&gt;G
      G-&gt;H
      H-&gt;I
      I-&gt;A
  
      {rank = same; A B C D}
      {rank = same; E}
      {rank = same; F G H I}
  }
  </code></pre>
  <p>How can I change the direction of those bottom lines in order to make it look like that?
