private void linkUp(Map<String, Node> nodes, List<String> knownSteps, StepImpl step) {
  LinkedHashMap<String, Step> nextSteps = step.getNextSteps();
  Node node = nodes.computeIfAbsent(step.getName(), Factory::node);
  if (step instanceof Scanner) {
    node= node.with(Color.BLUE,Style.lineWidth(3));
    nodes.replace(step.getName(), node);
  }
  knownSteps.add(step.getName());
  if (nextSteps.size() == 0) {
    return;
  }
  for (Step subsequentStep : nextSteps.values()) {
    if (!knownSteps.contains(subsequentStep.getName())) {
      // new node, need to recurse
      linkUp(nodes, knownSteps, (StepImpl) subsequentStep);  // yuck but I don't really want to expose next steps in interface either
    }
    Node nextNode = nodes.get(subsequentStep.getName());
    node = node.link(nextNode);
    // link returns an immutable copy of the node we just created, so we need
    // to throw out the original and keep the copy
    nodes.put(step.getName(), node);
  }
