title: Graphviz: change font for the whole graph?
body: <p>I am wondering if I can define an alternative font for the whole graph. </p>
  
  <pre><code>...
  digraph script_concept {
  graph [layout="dot",fontname="helvetica"];
  ...
  </code></pre>
  
  <p>According to this <a href="http://webcache.googleusercontent.com/search?q=cache%3acUK902XMrrsJ%3ahttps://mailman.research.att.com/pipermail/graphviz-interest/2008q3/005489.html/">1</a> older post the fontname atribute can be defined only separately:</p>
  
  <blockquote>
    <p>Nodes and edges don't inherit the font of the graph, you need to specify 
    them separately</p>
  </blockquote>
  
  <p>Is there any other way, how to define the font globally? </p>
