          data to understand how people communicate, collaborate, what
          information they exchange, what role they play in social
          groups has been tremendously simplified with the popularity of
          online networking systems such as Friendster, LinkedIn, or
          Facebook. Compared to data collected through polls and
          interviews, collected networks require less processing as they
          are directly stored digitally and open new opportunities for
          social scientists as they are far larger and often contain
          much richer information. However, this avalanche of data
          raises new challenges for their analysis: tools need to
          support a very large amount of data often evolving through
          time.</p>

          human brain is particularly effective at processing visual
          information, researchers in computer science developed a
          number of visual exploration system to analyze graphs and
          networks. In the last five years, an increasing part of the
          research in information visualization focused on graph
          visualization, tackling the problem from novel angles. Our
          research focused on alternative representations to node-link
          diagrams, supporting the analysis of denser networks as well
          as novel interaction techniques to scale to larger datasets.
          In this talk, I will present an overview of these novel visual
          exploration systems.</p>
