I found this pretty easy to do with ngraph.forcelayout[0]. I used it to build a basic VDOM-diff visualizing demo[1], which involved dynamically animating edge changes to a graph. If you need something like that, it's pretty easy with ngraph in case this library doesn't support it.
If you end up using this library, please let me know how it turns out! I'd love to see a demo of exactly what you're talking about. I ended writing quite a bit of mouse-event and panning/zooming code on top of ngraph so maybe this might be easier?
