title: How to insert mathematical symbols like Greek characters in a Graphviz dot file?
body: <p>I have an unique problem. I am using dot to represent a graph which is generic in nature. So, instead of using numbers, I was planning to use symbols like greek letters like alpha, beta, etc. I am curious to know how can we label nodes/edges in .dot file using some symbols? </p>
  
  <p>for example, </p>
  
  <pre><code>node1 -&gt; node2 [label= &lt;something here which will show up as symbol of beta&gt; style=dashed]
  </code></pre>
