Does anyone know about any JavaScript frameworks used for developing workflow-like diagrams? I'm looking for ways to show relationships between objects and to be able to drag the objects around within the browser. I'm looking for something similar to the functionality of Microsoft Visio.
Has anyone done anything similar with the Ext JS framework? This is all I've seen out there so far.

And I'd like to be able to drag components around like this.
