How Do I Create A Binary Tree Visulization In Mvc 3

Wrong. Standard tree view can show any arbitrary tree, including binary tree, of course (but not arbitrary graph which is not a tree).

Also, who told you that organization's hierarchy can be represented by a binary tree? It would simply mean that each supervisor supervises work of exactly two employees. Where did you see such organizational principle? :-)

[EDIT] In response to the discussion in comments:

I understand that the development of very complicated and/or highly customized UI could be prohibitively difficult, so I want to suggest one very simple idea: use a regular tree view, and it the presentation capacity of such a small thing as a tree view item seems too small to you, I will suggest how to add mode detail to the presentation. Actually, with ASP.NET/MVC, you have more flexibility in the presentation of tree view item, but first, let me explain the design I consider as the simpler one.

You can make a combination of this tree view, and say, a panel. Create, say, a user control with the tree view docked on left, and some panel on write (this is for the cultures using left-to-write writing, the opposite for some other). You may want to have a splitter control between them. Handle the events when you change the item selection in a tree view. On this event, each time it is invoked, take the tree node data and present it in full detail on your right. This design is very intuitive to the users and can be easily implemented on all kinds of UI libraries.

If you want to implement something much fancier, more unusual and non-standard, I can help you, too, but it will take a lot more work, so first look critically at your UI development skills.
