Best way to display and interact with a tree

I am trying to create an interface that is similar to the interface on this website for the skill tree:http://www.pathofexile.com/passive-skill-tree. What is the best way to go about doing this and have the same or similar user interaction. ie. you click on a node and it activate or deactivates it. The movement of the tree and zooming on it would be nice as well. I am somewhat new to this and am not familiar with all of the libraries that the SDK has to offer if anyone could give me pointers on where to look that would be great. I would like to try to stay away from webView as I am thinking about features I want to add. Thanks in advance just want to see what a good way to do this is.
