is there an option to do some transition animation for expanding nodes?

Hi
i was wondering if there is an option to do some animation when clicking on node and expanding its children like in d3 tree http://bl.ocks.org/mbostock/4339083?

It should be doable by enabling transitions (you can see them in the interactive demo):

// Custom transition function
function transition(selection) {
  return selection.transition().duration(500);
}

renderer.transition(transition);

Then if you add nodes / edges and re-run the layout they will transition into place.

Hi, I was playing around with this as well and it works great. The only thing that is somewhat disorienting is that the nodes often switch their order after "maximizing" a node. It would be really nice, if they would keep it. Is there any way to achieve this?
