Sorry for the late reply. Thanks for your inputs. Unfortunately, we do not have the privilege to use HTML5 and CSS3. As we may also have to support IE8...
@Rob: I have looked into few of those sites. Mostly it is about integrating drawing tools into our application. I am not sure, how we can use it in our applilcation. First, can we integrate them along with GWT. Second, programmatically draw the diagrams, give a Drag and Drop feature for the diagram, handle connectors..etc. It would be really great if we have suggestion with this design. Now, I have looked into lib-gwt-svg API. But, using which we can draw diagrams. But still, not enough documentation on how to make use of api. If anybody has any resources or links which they can share would be great.
