Abstract
In visualizing graphs as node-link diagrams, it is commonly accepted
and employed as a general rule that the number of link crossings
should be minimized whenever possible. However, little attention
has been paid to how to handle the remaining crossings in the
visualization. The study presented in this paper examines the effects
of crossing angles on performance of path tracing tasks. It
was found that the effect varied with the size of crossing angles.
In particular, task response time decreased as the crossing angle
increased. However, the rate of the decrease tended to level off
when the angle was close to 90 degrees. One of the implications of
this study in graph visualization is that just minimizing the crossing
number is not sufficient to reduce the negative impact to the minimum.
The angles of remaining crossings should be maximized as
well.
