JavaFx based web based diagramming tool?

[Manu dv]

Hi All,
We* needs to create a web based diagramming tool for various digram types such as use-case, class, BPMN etc.
I was wondering if any one here has tried out such a thing in java fx?
Any open source projects on this lines that you have heard of?

Basically I want to get a look at the code base a similar project. What I actually want to find out is - what kind of effort it would need to set up a generic diagramming frame work, by that I mean things like a tool pallette, drag-n-drop, auto-layout etc.


(*we=team of 2-3 people people who have some experiance in creating GEF based diagramming tool as eclipse plugin, but not much experiance in web except jsp,servlets etc)
