The paper "Interactive Revision Exploration using Small Multiples of Software Maps" by Willy Scheibel, Matthias Trapp and Jürgen Döllner has been accepted as a contribution to the 7th International Conference of Information Visualizations Theory and Applications (IVAPP 2016). The conference will be held in Rome from the 27th to 29th February.



To explore and to compare different revisions of complex software
systems is a challenging task as it requires to constantly switch between
different revisions and the corresponding information visualization. This paper
proposes to combine the concept of small multiples and focus+context techniques
for software maps to facilitate the comparison of multiple software map themes
and revisions simultaneously on a single screen. This approach reduces the amount
of switches and helps to preserve the mental map of the user. Given a software
project the small multiples are based on a common dataset but are specialized
by specific revisions and themes. The small multiples are arranged in a matrix
where rows and columns represents different themes and revisions, respectively.
To ensure scalability of the visualization technique we also discuss two rendering
pipelines to ensure interactive frame-rates. The capabilities of the proposed
visualization technique are demonstrated in a collaborative exploration setting
using a high-resolution, multi-touch display.
