The Hierarchy
Section outline
-
from Module 6: Multidimensional Visualization
Hierarchies are a common strategy to structure large amounts of information into nested manageable chunks. We find them everywhere, for example in taxonomies, tables of contents, file directories, or corporate organization charts.
In this section we will first have a look at different ways to viually represent hierarchies.
This is followed by a case study. We will look at a visualization method called the Parallel Coordinate Tree that combines multidimensional analysis with a tree structure representation. Distortion-oriented focus+context techniques are used to facilitate interaction with the visualization. It is a design study of a commercial application that was built, using this method to analyze and communicate results from large-scale customer satisfaction surveys.
Finally, the exercise puts things back into the big picture.
