title: Javascript library to generate workflow configuration diagrams
body: <p>I have a set of predefined flow diagrams, and I need a way to display the diagram and allow the user to interactively set inputs and/or properties at various nodes in the diagram.  The nodes/connections of the diagram are fixed and cannot be edited by the user.</p>
  
  <p>I know there are several options for diagram editors, but those would need heavy modification for what I need.  Any suggestions for javascript libraries/apps that would be able to do this?</p>
