SOFTVIS

Computer programming is a difficult skill for many students and visualizations may be used to foster learning. This paper presents a program animation system, PlanAni, that is based on the concept of the roles of variables. Roles represent schematic ...

We present a novel information visualization technique for the graphical representation of causal relations, that is based on the metaphor of color pools spreading over time on a piece of paper. Messages between processes in the system affect the colors ...

The paper presents a new 3D representation for visualizing large software systems. The origins of this representation can be directly traced to the SeeSoft metaphor. This work extends these visualization mechanisms by utilizing the third dimension, ...

Existing visualization tools typically do not allow easy extension by new visualization techniques, and are often coupled with inflexible data input mechanisms. This paper presents EVolve, a flexible and extensible framework for visualizing program ...

The Eclipse platform presents an opportunity to openly collaborate and share visualization tools amongst the research community and with developers. In this paper, we present our own experiences of "plugging-in" our visualization tool, SHriMP Views, ...

Dynamic software visualization is supposed to provide programmers with insights as to what the program is doing. Most current dynamic visualizations either use program traces to show information about prior runs, slow the program down substantially, ...

Software products are often released with missing functionality, errors, or incompatibilities that may result in failures in the field, inferior performances, or, more generally, user dissatisfaction. In previous work, we presented the GAMMA technology, ...

We describe GEVOL, a system that visualizes the evolution of software using a novel graph drawing technique for visualization of large graphs with a temporal component. GEVOL extracts information about a Java program stored within a CVS version control ...

Software technology for algorithm visualization (AV) has advanced faster than our understanding of how such technology impacts student learning. In this paper we present results of a multi-university study. We measured the effect of varying levels of ...

Algorithm visualization research for computer science education has primarily focused on expert-created visualizations. However, constructionist and situated theories of learning suggest that students should develop and share their own diverse ...

Program visualization holds great potential for conveying information about the state and behavior of a running program. However, barriers exist to the realization of this potential, and the limited knowledge about the factors that affect program ...

Software debugging is an extremely difficult cognitive process requiring comprehension of overall application behavior along with detailed understanding of specific application components. Typical debuggers provide inadequate support for this process, ...

End-user programming has become the most common form of programming today. However, despite this growth, there has been little investigation into bringing the benefits of software visualization to end-user programmers. Evidence from the spreadsheet ...

Optimizing the performance of shared-memory NUMA programs remains something of a black art, requiring that application writers possess deep understanding of their programs' behaviors. This difficulty represents one of the remaining hindrances to the ...

We are exploring the development and application of information visualization techniques for the analysis of new massively parallel supercomputer architectures. Modern supercomputers typically comprise very large clusters of commodity SMPs ...

An active research area in telecommunications concerns how to specify and control the addition of new services, such as call waiting or instant messaging, into existing software. One approach is to rely on a component-based architecture such as ...

Analysis and design of programs by using tools has emerged to a standard technique in object-oriented software engineering. Many of these tools claim to implement methods according to the UML standard and some of the tools provide automatic layout of ...

Whenever multiple representations or models of a system exist, there is the possibility of defining how they relate. In model driven software development, it is essential that these mappings are defined precisely and automated as far as possible: they ...

UML diagrams have become increasingly important in the engineering and reengineering processes for software systems. Of particular interest are UML class diagrams whose purpose is to display class hierarchies (generalizations), associations, ...

Class diagrams are among the most popular visualizations for object oriented software systems and have a broad range of applications. In many settings it is desirable that the placement of the diagram elements is determined automatically, especially ...
