RelationBrowser is a Flash application that provides a visually appealing view 
of relationships between objects. This plugin makes it trivial to use 
RelationBrowser with your rails application.

Requirements

You need to have "acts_as_nested_set" declared in the models you want to use
the plugin for. You'll also want to have parent/child relationships setup to
see anything useful!  Alternatively you can implement your own system for 
creating a hierarchy, you just need to provide the following methods: 
full_set, children, direct_children

I also recommend the BetterNestedSet plugin which extends acts_as_nested_set
with some further useful methods and optimizations:

In the controllers you want to use this on, add the following:
relation_browser :<model name>

Where :<model name> is optional and only needed if the model name doesn't 
match the controller name or can't be determined by the plugin.

Usage

You'll be automatically provided 3 new methods for your controller:

relationships = the main browser
root/<id> = the base relationships in XML that RelationBrowser can load
children/<id> = XML output for specific object relationships

Example:
  http://localhost:3000/things/relationships/1
  http://localhost:3000/things/root/1 <-- tree starting point XML output
  http://localhost:3000/things/children/3 <-- children of thing XML output
