title: How to generate graph of jenkins pipeline?
body: <p>In <a href="https://stackoverflow.com/questions/41077941/jenkins-pipeline-parallel-stages-merging-only-at-the-last-stage">this question</a> I've seen a nice graph which shows a jenkins pipeline:</p>
  
  <p><a href="https://i.stack.imgur.com/NaccI.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/NaccI.png" alt="enter image description here"></a></p>
  
  <p>But how can a generate such an image from my pipeline?</p>
  
  <p>Is there a special plugin or hidden button?
  I've found no such hint on the <a href="https://jenkins.io/doc/book/pipeline/" rel="nofollow noreferrer">jenkins pipeline documentation</a>.</p>
