PHP Tree Graph: Render graphical diagrams of hierarchical trees

This package can be used to render graphical diagrams of hierarchical trees of nodes.

There is a base tree class that manages an hierarchy of node objects.

A renderer sub-class takes care of traversing the tree and rendering a representation of each node in an image.

Each node may have associate a text, an image and desired width and height that it will occupy in the tree graphical diagram.

The colors of the image background, node, node links and node text are configurable. The node link style, node text font and node border width can also be configured.
