The idea for this is that the user can enter a twitter username and receive a directed graph showing which friends and followers they are connected to, and how those users are connected to each other.

The initial checked in code is far short of this. Only the given user's immediate friends are shown, followers are ignored. There are no connections between users other than the main user. Also, the rendering of the users only shows the id so far, not even the screen name, let alone an image.
