title: Implementing Flowchart using AngularJS and Canvas
body: <p>I am trying to implement a flowchart using AngularJS and Canvas.<br>
  Instead of providing users with a <code>UI</code> where they can drag'n'drop UI components, I want to build a command line tool where users will be entering a command to draw a circle, which will convert command to a JSON object and render that object in canvas.  </p>
  
  <p>Are there any libraries which I can use to render UI components using JSON Object?  </p>
