Abstract

Software visualization is a broad research area whose general goal is to enhance and promote the theory, realization, and evaluation of approaches to visually encode and analyze software systems, including software development practices, evolution, structure, and software runtime behavior. Software visualization is inherently interdisciplinary, drawing on theories and techniques from information visualization and computer graphics and applying these in the software engineering domain. This special issue on software visualization aims to bring together a community of researchers from software engineering, information visualization, computer graphics, human-computer interaction, and data science to discuss theoretical foundations, algorithms, techniques, tools, and applications related to software visualization. The special issue received 17 submissions of which 6 were accepted for publication (i.e., acceptance rate of 35.3%). Amongst the accepted papers, three correspond to extended versions of papers published in the IEEE Working Conference on Software Visualization (VISSOFT) 2021.
