Kurzfassung englisch:
The Dot-Based Contingency Wheel is an interactive visualanalytics
method designed to discover and analyze positive associations
in an asymmetrically large n m contingency table. Such tables summarize
the relation between two categorical variables and arise in both
scienti c and business domains. This paper presents the results of a pilot
evaluation study based on interviews conducted with ten users to assess
both the conceptual design as well as the usability and utility of the
Dot-Based Contingency Wheel. The results illustrate that the Wheel as
a metaphor has some advantages, especially its interactive features and
ability to provide an overview of large tables. On the other hand, we
found major issues with this metaphor, especially how it represents the
relations between the variables. Based on these results, the metaphor was
redesigned as Contingency Wheel++, which uses simpli ed and more familiar
visual representations to tackle the major issues we identi ed.
