- Software visualization
Software visualization [(Diehl, 2002; Diehl, 2007; Knight, 2002)] is concerned with the static or animated 2-D or 3-D [(Marcus et al., 2003)] visual representation of information about software systems based on their structure [(Staples & Bieman, 1999), size (Lanza, 2004)] , history [(Girba et al, 2005, Lopez et al., 2004; Van Rysselberghe et al., 2004)] , or behavior [(Kuhn et al., 2006, Stasko et al., 1997)] .
Typically, the information used for
visualizationis software metricdata from measurement activities or from reverse engineering. Visualization is inherently not a method for software quality assurancebut can be used to manually discover anomalies similar to the process of visual data mining. [(Keim, 2002; Soukup, 2002).]
The objectives of software visualizations are to support the understanding of software systems (i.e., its structure) and algorithms (e.g., by animating the behavior of sorting algorithms) as well as the analysis of software systems and their anomalies (e.g., by showing classes with height coupling).
Types of software visualization
Visualization of a single component
Tool for software visualization might be used to visualize source code and
quality defects during software development and maintenance activities. Their target is the automatic discovery and visualization of quality defects in object-oriented software systems and services. Designed as a plugin for an IDE (e.g., Eclipse) they visualized the direct relationship of a class and its methods with other classes in the software system and mark potential quality defects to warn the developer. A further benefit is the support for visual navigation through the software system.
Visualization of whole (sub-)systems
Other more powerful tools are used to visualize a whole system or subsystem to explore the architecture or to apply
visual data miningor visual analyticstechniques for defect discovery. Such tools are, for example:
