This talk introduces the speaker's techniques on space-filling tree and network visualization.
The former part of the talk introduces a tree visualization technique which represents hierarchy of
the tree structure as nested rectangular regions. The latter part of the talk introduces a network
visualization technique which clusters nodes according to their categories and connectivity,
and then displays the clusters as rectangular regions. Both techniques are based on a rectangle
packing algorithm which efficiently places the rectangular regions onto a display space. This talk
also introduces several applications of the tree and network visualization techniques.
