Diagraming relations between issues

Hi all:

A tracker I am working on has relations between issues. I have thrown
together a fast test to explore how to diagram the relationships.

The test can be viewed at:

  https://rouilj.dynamic-dns.net/demo/issue?@template=deps

Does anybody thing this sort of diagram would be useful?

Couple of things to note:

  hover over a node, it and all its descendents are highlighted

  nodes with bold text will hide the child nodes when clicked on.
     If the node has a link, click inside the node but not on the
     link to hide the children.

Quips, comments, evasions, questions, answers welcome.

(For those interested the relationship definitions are explained at:
