Graph API questions

1. What plugins (with sources) contain good examples of diagrams (Idea
graph API; class, database, sequence diagrams)?

Spring(bean dependencies), Struts, Seam(pageflow, pages), Jsf(navigation),
Jpa/Hibernate, Ejb

2. Where can I find graph Open API documentation? Examples?

see 1

3. Does graph API support diagram editing (for example, create link
between table elements), dragging diagram elements (listening of the
drop event)?

graph api supports all this actions by default. you have to only implement
2 interfaces: GraphDataModel<N, E> and GraphPresentationModel<N, E>(you
can use default implementation: BasicGraphPresentationModel<N, E>)

try Seam(pageflow designer - inplace editing, new dnd api, refactoring in
graph)
