Visualization techniques are commonly used in reverse engineering to better understand the underlaying design of software components. Our approach is to provide tools to help discover the architecture of a software by making use of innovative visualization and user interaction techniques. While a software is always evolving, there are ways to recover information about its structure. For instance, data mining can be applied to version control and bug tracking systems. To be able to see the software helps the architect predict and limit change impacts and costs. Our goal is to visualize the evolution of the software through time, while taking under account human factors and software engineering principles.

Compound graphs are often useful for modeling components of hierarchical systems. While node-link diagrams can be used to visualize these graphs, adjacency matrices have the advantage of eliminating occlusion between edges, even in dense networks. However, matrices do not reveal the hierarchy in a compound graph. To address this issue, we propose a novel hybrid visualization technique that combines an adjacency matrix with treemaps displaying portions of the hierarchy. A prototype is presented that illustrates these ideas and supports visualization of digraphs with weighted edges. Interaction techniques allow the user to reorganize the hierarchical groupings of elements and facilitates the exploration of links within the network. For example, in software engineering, the prototype enables browsing of links between source code modules to help discover the architecture of the software.
