Interactive Exploration and Analysis of Network Centralities

The use of network centralities in the field of network analysis plays an important role when the relative importance of nodes within the network topology should be rated. Such a single network can be easily rendered by the use of standard graph drawing algorithms. However, not only the exploration of one centrality might be important: the comparison of two or more of them is often crucial for a deeper understanding. When visualizing the comparison of several network centralities, we are facing new problems of how to visualize them in a meaningful way. In the life sciences, centrality measures help scientists to understand the underlying biological processes and have been successfully applied to different biological networks. Similar observations were made in the area of social network analysis.
