Hierarchy Chart is an easy to use, very specialized chart specially designed to display data that is logically arranged in several levels of hierarchy. In other words the displayed values are the leaves of a tree with constant depth.
The number of levels is unrestricted. The stucture can vary dynamically at runtime, nodes can be added and removed. The user can select the lowest visible level. This chart supports real 3D (rotating, sizing, perspective, ...) and dynamic change of data. The exact values at any level can be observed. Many more options are available.
