Tweet Wheel is a web-based visualization tool that shows your twitter contacts in a circular manner. It also shows how your contacts are connected with each other.

All you have to do is just go to Tweet Wheel. Enter your Twitter username and let Tweet Wheel do the rest of the work. After some time you will end up with a circle in which all your contacts and subsequently their contacts are presented in a circular manner.
But this process does take some time, so you need to be patient if you have a lot of contacts. Finally you get a circular picture showing all of your contacts with lots of lines showing which of your contacts follow one another on Twitter.
Point to be noted here that, since it involves a large number of contacts, the picture might become unreadable to the human eye but you can always scroll over any user name to get a close up look at their connections.
