title: Open source HTML5 JS library for flowchats
body: <p>I am planning to write an application that can allow me to draw flowchart like diagrams that can span over multiple dynamic rectangles (nodes) connected to N level of depth. Obvious  thought is to use a flowchat library to achieve the purpose. I like the examples give by <a href="http://gojs.net/latest/samples/flowchart.html">http://gojs.net/latest/samples/flowchart.html</a> but due to licensing terms I might not be able to use it.</p>
  
  <p>I am searching for opensource JS library so I can draw such diagrams on HTML5 canvas. Any thoughts?</p>
