The Interactive Decision Tree is a web-based tool that will walk users through a decision process by asking questions to lead them down the appropriate decision path. Think of it as a user-friendly flow chart.
Decision tree data is stored as standard XML and the "viewer" is made up of HTML, CSS and Javascript. The fact that the viewer uses only client-side code allows a decision tree to be hosted on any flavor of web server or even from a local computer.
Also included is a PHP-driven decision tree editor. This allows users to create the underlying XML data for a decision tree more easily than manually editing XML files. The editor requires PHP version 5 or higher to be running on your web server. Since the editor far simplifies the process of creating decision trees, it is recommended that you use it as well.

This section assumes you already have your web server up and running with PHP version 5 or greater.
- clone this repo
- Modify the permissions of the xml/ directory such that it is writable by your web server.
- Navigate to the editor page in your web browser:
e.g.
http://your-web-server.org/decision-tree/editTree.php(whereyour-web-serveris the domain name of your web server anddecision-treeis the directory created in step 2, above)
That's it. You should see a couple of example decision trees in the editor to experiment with.
