Org Charts for Contacts

I've seen that CRM now has the ability to build org charts rather than requiring any external plugins. 

I've been struggling to find any documentation or online training that specifically deals with org charts for contacts. 

I've been playing around with some of the settings but would rather not take the haphazard approach. 

I can see you can chose options like Colleague and Employee, but I need to be able to define the reporting relationship structure better

Where can I find information on this?

A lot of the material I've seen so far just focuses on company relationships, not specifically employee/contact relationships

All response appreciated.
