Call for Papers Software visualization is a broad research area encompassing concepts, methods, tools, and techniques that assist in a range of software engineering and software development activities. Covered aspects include the development and evaluation of approaches for visually analyzing software and software systems, including their structure, execution behavior, and evolution. The VISSOFT IEEE Working Conference on Software Visualization continues the history of the ACM SOFTVIS Symposium on Software Visualization and the IEEE VISSOFT International Workshop on Visualizing Software for Understanding and Analysis. The conference focuses on visualization techniques that target aspects of software maintenance and evolution, program comprehension, reverse engineering, and reengineering, i.e., how visualization helps professionals to understand, analyze, test and evolve software. We aim to gather tool developers, experts, users, and researchers from software engineering, information visualization, computer education, computer graphics, and human-computer interaction to discuss theoretical foundations, algorithms, techniques, tools, and applications related to software visualization. We seek technical papers, empirical studies, applications, or case studies and provide a platform for presenting novel research ideas and tools. Topics of interest include, but are not limited to: • Innovative visualization and visual analytics techniques for software engineering data, such as, • source code • static and dynamic dependencies • software evolution and repositories • software documentation • web services • protocol, log, and performance data • configuration management, DevOps, production systems • parallel techniques • database schemes • software security and privacy issues • workflow and business processes • Visualization to support program comprehension, software testing, and debugging • Interaction techniques and algorithms for software visualization • Visualization-based techniques in computer science and software engineering education • Integration of software visualization tools and development environments • Empirical evaluation of software visualization • Industrial experience on using software visualization • Task-specific visualization support for software engineering tasks Papers are solicited that present original, unpublished research results and will be rigorously reviewed by an international program committee. In addition to technical papers, VISSOFT features a New Ideas or Emerging Results (NIER) track and a Tool track related to the same list of topics suggested above. All accepted submissions will appear in the conference proceedings and the IEEE Digital Library. NIER papers and Tool Demo papers (up to 5 pages): We accept two types of paper submissions: NIER contributions (New Ideas and Emerging Results) and Tool contributions. The NIER contributions describe work-in-progress and preliminary exciting results. Authors should include open questions and even provocative hypotheses to get early feedback on their research ideas or even support through new research collaborations. NIER papers have to be maximum 5 pages long (including bibliography and annexes). Tool contributions describe the design or actual utilization of software visualization tools, with a focus on relevant tool construction aspects or the use of the tool for gaining new insights. Authors should be prepared to demonstrate their tool at the conference. The submission may also contain a link to a screencast (video). Tools papers have to be maximum 5 pages long (including bibliography and annexes).
