Dynamically generating color families and assigning colors to differentiate multi-level hierarchical groups Tree diagrams generated by existing cluster analysis programs do contain relationship information, but in that format the information is not easy to understand at a glance. The proposed solution makes the diagrams much easier to understand by using automatically calculated color sets to distinguish the groups and subgroups. Figure 1 below is a tree diagram representing relationship information from a cluster analysis of a card-sorting exercise. Two pairs of items, and the paths connecting the members of each of these pairs, have been highlighted for illustration purposes. (A standard tree diagram would not contain this highlighting.) The first pair ("Aptiva"* and "Aptiva's ease of use") are connected by a path that remains relatively close to the origin, indicating that these items were grouped together by most of the participants. The line connecting the second pair ("Desktop" and "UI Fundamentals") travels all the way out to the maximum distance of 1.00. This path indicates that some members of each of the groups to which the items belong were always placed in separate groups in the card-sorting exercise.
