It can query a MySQL database table that contains records of nodes of a tree of elements that form a hierarchy.

Hierarchies represent relations between people or other types of related entities. The hierarchy structure determines which entities are in command of other entities.

Hierarchies can be stored in databases using table records that express what entities are below or above in the hierarchy tree.

This class can retrieve a hierarchy tree structure from a MySQL database table to easily visualize using the Google Charts API.
