Some preliminary work has been done on subjects’
preference for different aesthetics in UML class and
collaboration diagrams (Purchase et al. 2000), revealing
that users preferred diagrams with fewer bends and
crosses, shorter edge lengths and an orthogonal structure.
However, that experiment only looked at subjects’
personal preference for the aesthetics, rather than their
performance on UML related tasks.
This paper describes two experiments that aimed to
determine which graph drawing aesthetics are most
important for the display of UML class diagrams, not
with respect to computational efficiency, designers’
preference, or even subjects’ preference, but with respect
to the extent to which the aesthetics produce diagrams
that are easy for subjects to understand. The...
