Abstract:

This paper contains a short introduction to the use of the LaNet-vi visualization tool for the analysis of large sparse networks. LaNet-vi is based on the $k$ -core decomposition, whose characteristics are summarized in this paper along with the main features of the developed algorithm and layout. We elucidate the relation among the layout's features and the graph topological properties. Finally we show how LaNet-vi's visualizations can be used to exploit the network organizational features: hierarchical relationships, shells interconnectivity or nodes clustering provide global structural information at a glance, yielding a rapid method for graphs fingerprinting.
