Abstract
Recent research has indicated that human graph reading performance can be affected by the size of
crossing angles. The aesthetic of crossing angles is closely related to another aesthetic factor: edge
crossings. Although the number of edge crossings has been previously identified as the most important
aesthetic, its relative impact on human graph reading, compared to the size of crossing angles, has
not been investigated. In this paper, we present an exploratory user study investigating the relative
importance between crossing number and crossing angle. This study also aims to further examine the
effects of crossing number and crossing angle not only on task performance measured as response
time and accuracy, but also on cognitive load and visualization efficiency. The experimental results
reinforce the previous findings that the two aesthetics each significantly affect performance of human
graph reading. Further, in terms of the relative importance, the study demonstrates that given the current
setting of the user study, the number of edge crossings is relatively more important than the size of
crossing angles. To be more specific, crossing number and crossing angle together explain about 40%
of the variance in response time, mental effort and visualization efficiency, with about 83% of the
explained variance being attributed to crossing number. In regard to response accuracy, crossing number
and crossing angle together explain about 14% of the variance, with a slightly larger portion of the
explained variance being attributed to crossing number.
