AngularJS Friendly Library for node edge diagrams (with layout)
<p>I'm looking for a JS library that can render interactive node edge diagrams.
Ideally it should integrate well with AngularJS, but I can always create a wrapper for one if it doesn't exist.</p>

<p>Ideally I'd use: <a href="http://gojs.net/" rel="nofollow">http://gojs.net/</a>, but the cost is prohibitively high.</p>

<p>Does anyone have any recommendations for an alternative?</p>
