title: Graphviz (neato) label overlaps edge problem
body: <p>I have simple network generated with graphviz(neato):</p>
  <pre><code>  digraph G{
        edge [len = 1.5, fontcolor=blue];
        0 -&gt; 1 [label=&quot;0/8&quot;];
        0 -&gt; 2 [label=&quot;0/7&quot;];
        1 -&gt; 3 [label=&quot;0/6&quot;];
        2 -&gt; 1 [label=&quot;0/2&quot;];
        2 -&gt; 4 [label=&quot;0/7&quot;];
        3 -&gt; 2 [label=&quot;0/5&quot;];
        3 -&gt; 5 [label=&quot;0/10&quot;];
        4 -&gt; 3 [label=&quot;0/4&quot;];
        4 -&gt; 5 [label=&quot;0/2&quot;];
    }
  </code></pre>
  <p>This code generates:
  <a href="https://i.stack.imgur.com/1EGIP.jpg" rel="nofollow noreferrer">network</a></p>
  <p>As you can see, the label for 0 -&gt; 1(3-&gt;2 and 4-&gt;5 too) edge overlaps the edge. Is there any way to avoid it?
  I have changed len and fontcolor to make a contrast, but still that is not satisfying.</p>
