Different visual representations of a tree can provide different views
of the same data, leading the viewer to obtain different information,
and gain different knowledge. Any visual representation of a tree,
therefore, may potentially obscure some important aspects of the data,
or sometimes even mislead the user.
We create Tree-Panels, a tree visualization system that provides
four simultaneous visualizations of a tree.
Our user study shows that different tree representations
used in Tree-Panels can uncover different and complementary
information about the data.
