Integrating Visualization in Software Development
January 2011 (expected)
In this Ph.D. thesis, we propose to integrate visualization into software development
environments. In doing so, programmers are able to directly assess software quality by using
different views and they are able to immediately evaluate the impact of their modifications in
real time. This strategy replaces the paradigm of decoupled analysis and coding activities, and
proposes an alternative to writing programs in pure text format. Our visualization, presented in
the same window as the development environment, reacts instantly to modifications by updating
all kinds of metric values and presenting them graphically. The visualization organizes several
views along three axes: granularity, context, and software evolution. Movements between views
are based on coherence principles such that users can focus on the same elements in each view
and keep track of their main objective in all these views. A conducted study shows that
programmers use the tool in an efficient way to solve quality related problems.

Representing Software Quality for Large Programs
December 2006
In this M.Sc. thesis, we approach software analysis from the angle of visualization. The analysis
is based on pre-computed software metrics associated with graphical characteristics. Java classes
are presented as 3D boxes with the following graphical characteristics: color, height, rotation.
These classes are arranged on a plane according to their package architecture with the help of
space optimizing algorithms. The visualization features are inspired by perception principles so
that it can be useful for quality analysis where an expert’s opinion is required. Our comparative
study shows that our layouts are more effective than a naïve layout and that our approach is
more efficient than manual inspection.
