Source code visualization (SourceViz)

The document outlines an agenda for a presentation on source code visualization. It discusses the problem of complex software systems being intangible and invisible. As a solution, it proposes visualizing source code elements and metrics to provide insight. It reviews related work using graphs, charts and cityscapes. It then introduces SourceViz, a tool that extracts metrics from Java source code and visualizes class relations, complexity and other metrics at the package, class and method level using various techniques. The conclusions state that visualization provides an efficient way to understand structure and interpret metrics. Future work includes evaluating and visualizing reusability, refactoring and re-engineering opportunities.
Source code visualization (SourceViz)
- 2. Agenda for Today Problem Area Solution- Software Visualization Source Code Visualization Related Work A glimpse of SourceViz Module1- Class Explorer Module2- Visualization(Charts, Class-Method level, Single Class, All Classes’ Cohesion) Module3- Package, Classes(compute) Conclusion Future Works
- 3. Problem Area Complex hierarchal systems Intangible nature of software Can't have detailed insight into the source code
- 4. Solution- Software Visualization "The use of computer graphics to facilitate the understanding of software" Provides a physical shape to software Helps in understanding invisible aspects of software Deals with static and dynamic aspects of software
- 5. Source Code Visualization Visualize several elements of source code Highlight invisible features i.e. static properties of software
- 6. Related Work Known visualization techniques in the literature: Bar Charts and Pie Charts Matrix Views Graphs Cityscapes Data Sheets
- 7. Related Work (contd.) Graph based visualization techniques have been most commonly used. Tool Support: MetricView (visualize a few metrics by mapping them on UML diagrams, shows very limited amount of classes in a single view) SolidFX (visualize software metrics for C/C++ platform) Polymetric View (visualize class hierarchy relations only at multi-levels).
- 8. Related Work (contd.) Cityscape View A graph based visualization technique Three dimensional extensions of matrix views Tool Support: CodeCity Codstruction These tools visualize software metrics but do not visualize class relations and hierarchy
- 10. Research Methodology Basic vs. Applied Qualitative vs. Quantitative
- 11. SourceViz A source code visualization tool, that will extract software metrics compute these metrics visualize class relations compute cyclomatic complexity and then visualize them
- 13. Visualization Techniques Bar & Pie Charts JFree Chart Visualize metrics of a specific file of project Graph Representation Package-Method level hierarchy Class-Class relation (full project cohesion) Class-Method relation (single class cohesion)
- 17. Full Project Cohesion (Class Level)
- 22. Conclusions Source Code Visualization provide the users an efficient manner to: understand structure of source code interpret class relations and other metrics to give a high level view of the system determine the complexity of the source code
- 23. Future Works Evaluate and Visualize Reusability Opportunities Refactoring Opportunities Re-engineering Opportunities Support to object oriented languages other than Java
