I was going to develop a tree view of ruby class hierarchy using the  
FreeMind software. I was thinking of basing it on  
[http://www.insula.cz/dali/material/rubycl/](http://www.insula.cz/dali/material/rubycl/) but I want to show pretty  
much everything with Object in the middle then have types of Objects  
branching off. So, for example, I would have branches on Object like  
Object\_Data\_Types, Object\_IO, Object\_Exceptions, etc. Then on  
Object\_Data\_types I would have branches like Numeric, Date, etc.

I think this would be useful, do you? Has this already been done?

Thank you.
