title: How to change Google Organization Chart link line color & thickness?
body: <p>I am fiddling around with <a href="https://developers.google.com/chart/interactive/docs/gallery/orgchart" rel="nofollow noreferrer">google's organization chart</a> in javascript but I can't figure out how to change the link lines' color and thickness. The documentation only talks about styling the nodes but there is nothing about the links connecting them.</p>
  
  <p>How do I style the links?</p>
