    Visualizing the Flow of Users on a Wireless Network



    This information visualization project depicts the flow of users within the various access points of the eduroam network of the University of Coimbra. The developed application allows the visualization of an interactive graph (see Figure 1), which covers a certain time span, and animates the changes in the network’s flow of information over time. The nodes of the graph represent access points and the links represent transitions of users between them. A transition is registered when a user stops the connection to an access point and connects to another one. Clustering is used to merge access points that are deeply connected, promoting the visual clarity of the artifact while providing additional information to the viewer.
