Twitwheel is a tool available in http://www.twitwheel.com/ to visualize graphically the interactions that occur between Twitter accounts.
It is a tool to study the social networks a very basic level.
It presents information using a circular graph connections between their points (nodes), associated with a user account. For example, if we see the data associated with the account of the UPM, user @ la_upm, we access the browser using the URL: “http://www.twitwheel.com/la_upm”
The graph has a certain ability to interact; if we select a node, we can see the messages sent from it on the right side of the diagram. If you select an avatar, jump to the diagram associated with it.
