title: How to use Community Visualization - Sankey Diagram?
body: <p>I've quite a few different combinations for the dimensions (in the property bar) but can't seem to get the Sankey diagram to work after I copy it, shown here: <a href="https://developers.google.com/datastudio/visualization/" rel="nofollow noreferrer">https://developers.google.com/datastudio/visualization/</a></p>
  
  <p>What is the format of the data it needs? Also, how many nodes can it support - can I do 4 nodes?</p>
