EgoNet is a software to conduct interviews in which the personal networks of respondents are collected. EgoNet2GraphML is a small graphical java program that can (1) convert EgoNet interviews into GraphML files (that can be opened with visone) and (2) cluster, aggregate, and visualize collections of personal networks using the methodology proposed in: Ulrik Brandes, Jürgen Lerner, Miranda J. Lubbers, Chris McCarty, and Jose Luis Molina Visual Statistics for Collections of Clustered Graphs. Proc. IEEE Pacific Visualization Symp. (PacificVis'08), 2008.
