Hi,
mir fehlt der Kontext - wo wird das Bild referenziert? Was soll es zeigen?
At the Darmstadt University of Technology Ivica Aracic's research is concerned with the question: can graph-based software visualization facilitate reasoning on the quality of software architectures?
In the course of Ivica's work he has analyzed the architectures of several products including Prefuse, JEdit, and The Spring Framework.
On the Spring developer list Ivica noted, "after analyzing Spring I was surprised to find there is not a single cycle in the dependency graph at the architectural level." (see screenshot)
