This article is a survey of program visualization systems intended for teaching beginners
about the runtime behavior of computer programs. Our focus is on generic systems that are …

Program comprehension is an important activity in software maintenance, as software must
be sufficiently understood before it can be properly modified. The study of a program's …

We present a program visualization tool called Jeliot 3 that is designed to aid novice
students to learn procedural and object oriented programming. The key feature of Jeliot is …

This paper proposes a methodology and instrumentation infrastructure toward the reverse
engineering of UML (Unified Modeling Language) sequence diagrams from dynamic …

Software maintenance activities require a sufficient level of understanding of the software at
hand that unfortunately is not always readily available. Execution trace visualization is a …

Program visualization is one of the various methods developed over the years to aid novices
with their difficulties in learning to program. It consists of different graphical–often animated …

Visualization tools have proven to be useful for enhancing novice programmers' learning.
However, existing tools are typically tied to particular programming languages, and tend to …

This paper presents a novel reverse engineering technique for obtaining real-life event logs
from distributed systems. This allows us to analyze the operational processes of software …

Reverse engineering of sequence diagrams refers to the process of extracting meaningful
information about the behavior of software systems in the form of appropriately generated …

GXL (Graph eXchange Language) is an XML-based standard exchange format for sharing
data between tools. Formally, GXL represents typed, attributed, directed, ordered graphs …
