OnionUML: An Eclipse plug-in for visualizing UML class diagrams in onion graph notation

Abstract

This paper presents OnionUML, an Eclipse plug-in that reduces the number of visible classes in a UML class diagram while preserving structure and semantics of the UML elements. Compaction of class elements is done using onion graph notation. The goal is that developers will be able to view and understand subsystems of a large software system while being able to visualize how that subsystem fits into the whole system.
