UI diagram layout

Wanted to generate a UI diagram (with nice layout) depicting relationships amongst network components. Which is the best Java based API to do such layouts with minimum fuss and light codebase.

From stackoverflow

• Any uml tool should do the work

  Take a look at UMLet or NetBeans as UML editors made in Java.

  (BTW, Visio Is usually the standard tool for that job)

• If you're logging for a Java API that can do layouts (e.g. arrange boxes in a hierarchical fashion without overlap), check out JGraph.

• yWorks. http://www.yworks.com/en/index.html

• JFreeChart rules! :) http://www.jree.org Lib itself free, docs costs money, but really not much.
