Abstract:


Several techniques for visualization of dynamic graphs are
based on different spatial arrangements of a temporal sequence of node-link
diagrams. Many studies in the literature have investigated the importance
of maintaining the user's mental map across this temporal sequence,
but usually each layout is considered as a static graph drawing
and the effect of user interaction is disregarded. We conducted a
task-based controlled experiment to assess the effectiveness of two basic
interaction techniques: the adjustment of the layout stability and the
highlighting of adjacent nodes and edges. We found that generally both
interaction techniques increase accuracy, sometimes at the cost of longer
completion times, and that the highlighting outclasses the stability adjustment
for many tasks except the most complex ones.
