  <p><em>Image link is not available anymore.</em></p>
  <p>I tried this:</p>
  <pre><code>digraph Alf {
  size = &quot;15&quot;;
  node [ shape = record , style=filled, fillcolor=&quot;#efefef&quot;,fontname=Helvetica, fontsize=10.5, fontcolor=&quot;#2b2b2b&quot;, height=0.25, width=1, penwidth=0 ];
  edge [arrowhead=normal,arrowsize=0.5,len=0.5, color=&quot;#bfbfbf&quot;];
  
  root [label =&quot;Autors i teories de la comunicació no verbal&quot;];
  1 [ label=&quot;es concreta en&quot;, fontcolor=&quot;#00aeef&quot;, fontsize=9.5, fillcolor=white ];
  
  root-&gt;1;
  1-&gt;&quot;LOE&quot; 
  1-&gt;&quot;Estratègies&quot;;
  1-&gt;&quot;Activitats&quot;;
  1-&gt;&quot;Recursos&quot;;
