PHP Tree Graph Ext 0.1 (Default branch)
04-16-2008
PHP Tree Graph Ext is a PHP package that can be used to render graphical diagrams of hierarchical trees of nodes. Each node may be associated with a title, text, an image, and a desired width and height that it will occupy in the tree's graphical diagram. The colors of the image background, node, node links, and node texts are configurable. The node link style, node text font, and node border width can also be configured. The user can also choose which node will be the root, such that all nodes that aren't a descendant of the root won't be shown. License: GNU Lesser General Public License (LGPL) Changes:|
