Does anyone know a js or jquery flow chart plugin

Hi all,

I was thinking about adding a user generated flow chart for a site. I thought there would be libraries available offering flow chart functionality - how wrong I was.

Now I realize it is actually quite complicated to code from scratch, I was hoping for click and drag features of some sort but can live without them. Has to be user friendly. In fact even a flow diagram generator would do, I can always think up a UI of some sort to deal with the needs of the library.

Have now been searching for quite some time and can't find anything of any use.

Does anyone have any links to any potential resources or do I really have to roll my own. I am not sure I am wedded to the idea enough to spend much time on it, and my JS is functional, but not brilliant.

Even a mind map type thing would do, just wanted to offer that way of planning (flow chart or mind map type) for my users.

Any suggestions or ideas warmly welcomed,

Thanks in advance, Google and Bing have failed me,

Best wishes,

Paul.
