Missing sourcePoint and targetPoint

[Alex Morega]

In some cases, the return value of the layout algorithm is missing sourcePoint and targetPoint for an edge. Here is an example input and output: https://gist.github.com/mgax/13c0d1ff02a6c9bcc5ed.

Your specified edge crosses a hierarchy boundary (as B is a child of A and C is on the same level as A). Our algorithm does (by default) not support cross hierarchy edges, they are ignored completely.

We however offer a layout option layoutHierarchy that supports those edges. You add it to the properties of the root level node like this:

{
  "properties": {"layoutHierarchy": true},
  "children": {
  [...]
}

Let me know if this helps.

I've added "options": {"layoutHierarchy": true} to the $klay.layout call, that did the trick, thanks!

For future reference, we changed layoutHierarchy to be true by default.
