title: Pie charts node cytoscape
body: <p>I have a .txt table like this:</p>
  
  <pre><code>column1: Source Node
  column2: Target Node
  column3: Edge attribute
  column4: Source Node attribute 
  </code></pre>
  
  <p>the 4th column is a list of floating point numbers like this:</p>
  
  <pre><code>example: 0.01,0.8,0.1,0.9
  </code></pre>
  
  <p>these values are percentage values (the sum of all the values in one row is =1), since all the nodes are derived from different conditions. </p>
  
  <p>What I would like to have is a cluster in which each single node is a pie chart, and the arc lenght of each slice is the percentage values. So in the example before I would have a pie chart with arc lenght 1%, 80%, 10%, 9%</p>
  
  <p>How can I do it? If I try to set it in the Image/Chart properties in the Style menu I get some weird error and the nodes disappear from the cluster. Is there a tutorial? Something I can use? I am using Cytoscape 3.3 
  Thanks for your help!</p>
