Git repositories quickly become highly complex structures that do not reveal much human-readable information beyond files and folders of active branches. This paper introduces VisGi, a tool to abstract and visualize the branch structure of Git repositories, as well as their folder trees. By interpreting branches as groups of aggregated commits, their dependencies are condensed into a directed acyclic graph, and displayed using graph layout strategies. Additionally, Sunburst diagrams are used to display the current content of these branches, the differences between each two branches, as well as the evolution along any singular selected path through the repository.

Most software development tools and applications are designed from a single-user perspective and are bound to the desktop and Integrated Development Environments (IDEs). These tools and applications make it hard for developers to analyse and interact with software artifacts collaboratively. We present SourceVisa multi-user collaborative software visualization application for use on large multi-touch tables. We describe the design and visualization features of SourceVis, present findings from a user study, and discuss the implications for building collaborative software visualization applications.

The increasing code complexity in modern enterprise software systems exceeds the capabilities of most software engineers to understand the system's behavior by just looking at its program code. Large software landscapes, e.g., applications in a cloud infrastructure, further increase this complexity. A solution to these problems is visualizing the applications of the software landscape to ease program comprehension and to understand the respective communication. An established visualization concept is the 3D city metaphor. It utilizes the familiarity with navigating a city to improve program comprehension. Dynamic analysis, e.g., monitoring, can provide the required program traces of the communication. In this paper, we present our live visualization approach of monitoring traces for large software landscapes. It combines a landscape and a system level perspective. The landscape level perspective provides an overview of the software landscape utilizing the viewer's familiarity with UML. The system level perspective provides a visualization utilizing the city metaphor for each software system.

The increasing code complexity in modern software systems exceeds the capabilities of most software engineers to understand the system's behavior by just looking at its program code. The addition of concurrency issues through the advent of multi-core processors in the consumer market further escalates this complexity. A solution to these problems is visualizing a model of the system to ease program comprehension. Especially for the comprehension of concurrency issues, static information is often not sufficient. For this purpose, profiling and monitoring can provide additional information on the actual behavior of a system. An established visualization approach is the 3D city metaphor. It utilizes the familiarity with navigating a city to improve program comprehension. In this paper, we present our trace-based SynchroVis 3D visualization approach for concurrency. It employs the city metaphor to visualize both static and dynamic properties of software systems with a focus on illustrating the concurrent behavior. To evaluate our approach, we provide an open source implementation of our concepts and present an exemplary dining philosophers scenario showing its feasibility.

Understanding the root of a performance drop or improvement requires analyzing different program executions at a fine grain level. Such an analysis involves dedicated profiling and representation techniques. JProfiler and YourKit, two recognized code profilers fail, on both providing adequate metrics and visual representations, conveying a false sense of the performance variation root. We propose performance evolution blueprint, a visual support to precisely compare multiple software executions. Our blueprint is offered by Rizel, a code profiler to efficiently explore performance of a set of benchmarks against multiple software revisions.

Navigating through software is an integral part of software development. Studies have identified that during navigation programmers often become disoriented and lose task awareness. To mitigate this, the method-flow visualisation technique displays traversed methods in adjacent editor columns. This paper presents the Visuocode software development environment, which is an implementation of method-flow that, in addition to navigation, supports program composition.

Data visualisation with high expressive power plays an important role in code comprehension. Recent visualisation tools try to fulfill the expectations of the users and use various analogies. For example, in an architectural metaphor, each class is represented by a building. Buildings are grouped into districts according to the structure of the namespaces. We think that these unique ways of code representation have great potential, but in our opinion they use very simple graphical techniques (shapes, figures, low resolution) to visualise the structure of the source code. On the other hand, computer games use high quality graphic and have high expressive power. A good example is Minecraft, a popular role playing game that supports both high definition, photorealistic textures and long range 3D scene displaying. Additionally, it provides great extensibility and interactivity for third party software. In this paper, we introduce our mission to create a virtual world of source code in which developers and other stakeholders could explore and evaluate their project collaboratively in a virtual Minecraft world. Code properties are represented by graphical primitives offered by the game engine, and various interactivity features are planned. Besides challenges of the implementation there are some fundamental research issues considering the selection of a set of visual elements and mapping to source code properties. These elements have to be compatible not only with the visualisation and with the data model but also with the thinking of developers.

Developers and managers need to be aware of the emotional climate of the projects they are involved to take corrective actions when necessary and to have a better understanding of the social factors affecting the project. With the growing trend of distributed teams and textual communication this type of awareness is more difficult to obtain and maintain. We propose to improve emotional climate awareness in software development projects by means of a visualization prototype which includes general and detailed views of the topics and emotions expressed in software project collaboration artifacts. We performed an initial case study in which the mailing list content of a software project was visualized. The study suggests that the length, frequency and emotion diversity of the exchanged content varies according to the project phase. However, a more extensive evaluation needs to be made.

Software systems are often modeled and visualized as graphs in order to understand their higher-level structure: code entities are connected by dependencies or couplings. However, when only considering one type of code coupling such as method calls, the understanding gained stays limited to this specific aspect. Encoding multiple types of code coupling in the graph promises to broaden the understanding. Different approaches already exist for visually discerning those types in graph diagrams. In this paper, we study two of these techniquesa node-link and a matrix approach-in a realistic scenario where the classes and interfaces of a system are connected by six different types of code coupling. The explorative user study that we conducted with interactive versions of the two visualizations focuses on getting an insight on how software developers use the visualizations for understanding an unknown system. We classified typical visual structures that the participants were able to identify and connected these structures to software engineering problems. Despite the fundamental difference in approach, the participants identified the same graph structures targeting similar tasks with both visualizations.

Interactive software visualization offers a promising support for program comprehension, including program dynamicity. We present, the extension of an existing visualization tool with heat maps to explore the time and other dimensions of software. To this end, we first propose a framework to unify the two main software dynamicities, execution and evolution. Then, this unified framework is exploited to define a visualization environment based on heat maps. We illustrate our approach on two comprehension tasks: understanding the behavior of programmers during the evolution of an application and understanding class contributions in use cases. The case studies show that the heat-map metaphor contributes to answer, more easily, many of the questions important to program comprehension.
