Tool for visualizing software architecture
An automated tool for partitioning the source code of a software system at heuristic architectural boundaries identified by a bug-reporting process, and for representing the architecture of the software system as a set of visual attributes without constraining the representation to any particular predefined architectural style. The attributes are visualized applying multi-dimensional mapping techniques to software components to generate visual maps of the relationships and interactions among software components that cannot be easily understood or assimilated in a non-graphical form.
