title: UE4 Blueprint Interface in Javascript
body: <p>I am attemping to make a graph like interface in javascript (probably utilizing D3.js or YUI), to mimic (somewhat) the interface of Unreal Engine 4's blueprint editor. It is showcased here:</p>
  
  <p><a href="https://www.youtube.com/watch?v=s5pIrpI7py8" rel="nofollow">UE4 Blueprint Demo</a></p>
  
  <p>Is there any library in javascript that basically does this , or if not , which library would you recommend me to study to create this. </p>
  
  <p>When I say it needs to be like that, I don't mean the EXACT look and feel, just the general Node 1 has x inputs y outputs, connect output 2 to input 3 of node 2, etc.. Thank you!</p>
