title: Sankey amcharts nodes are not being aligned well
body: <p>So I'm working with amcharts v4 and Sankey diagram.
  I'm trying a dataset that is quite simple but I have the node 500 and 652 on same level and causing some visual issues as in the picture below.
  I've tryied to arrange differently the dataset but having same issue.
  Anyone can help?
  Is even possibile to reduce the links width in order to make it fit better? (tryied everything from SankeyLink but with no results)</p>
  <pre><code>[{from: '100', to: '200', value: 1},
  {from: '200', to: '450', value: 1},
  {from: '450', to: '652', value: 1},
  {from: '450', to: '652', value: 1},
  {from: '652', to: '500', value: 1},
  {from: '652', to: '500', value: 1},
  {from: '500', to: '650', value: 1},
  {from: '500', to: '650', value: 1}]
  </code></pre>
