Most applications in physical calculations provide
powerful multivariate outputs but use rather simple
visual representations (diagrams) without the
possibilities to explore the resulting data sets.
Interdependences in the data are overlooked or stay
unseen and the analysis is very time-consuming, because
of the difficulty and complexity for users to grasp the
In this paper we present a tool which combines a
visual structure recognised by the physical community
with interactive information visualization techniques to
support the analysis of decay chain calculations. In a
case study we showed that our tool helped experts in the
field to analyse radioactive decay chains where the
representation of results is more concise and conclusions
are easier drawn.
