title: Graphviz: label on the left side
body: <p>in case I use the following Graphviz code, a simple graph will be created
  which shows the label on the right hand side.</p>
  
  <pre><code>digraph lable_on_the_right_side {
  
     /* define nodes */
  
     node [color=lightblue2, style=filled, fontname=Arial];
  
     a [label="S1"];
     b [label="S2"];
  
  
     /* define edges */
  
     a -&gt; b [label="Label on the right side"]
  
  }
  </code></pre>

  <p>Is it possible to let the label appear on the left side instead?
  If yes, what would the code need to look like?</p>
