  <p>In perfect world It would look a little more like <a href="https://fs.linkmeup.ru/ftree-vis/index.html" rel="nofollow noreferrer">this fat tree with Tree Depth set to 3 and
  Ports per Switch set to 6</a>, yet FDP is more or less OK... Only thing I want to change is the mess in the centre: How to set minimal distance between nodes in dot for FDP rendering?</p>
