title: dashed nodes html-like labels graphviz
body: <p>I have a dot graph with html-like label nodes and I am trying to have as node's appearance for some of them "dotted" and "dashed".</p>
  
  <p>I know it is possible to modify the appearance of a polygon-based or record-based shape using the style attribute, for example style = dotted or style = dashed.</p>
  
  <p>How can I do the same for the html-like label?</p>
