The program dependence graph (PDG) itself and the computed slices within the program dependence graph are results that should be presented to the user in a comprehensible form, if not used in subsequent analyses. A graphical presentation would be preferred as it is usually more intuitive than textual ones. This work describes how a layout for the PDGs can be generated to enable an appealing presentation. However, experience shows that the graphical presentation is less helpful than expected and a textual presentation is superior. Therefore this work contains an approach to textually present slices of PDGs in source code. The innovation of this approach is the fine-grained visualization of arbitrary node sets based on tokens and not on complete lines like in other approaches. Furthermore, a major obstacle in visualization and comprehension of slices is the loss of locality. Thus, this work presents a simple, yet effective, approach to limit the range of a slice. This approach enables a visualization of slices where the local effects stand out against the more global effects. A second, more sophisticated approach visualizes the influence range of chops for variables and procedures. This enables a visualization of the impact of procedures and variables on the complete system.
