For more information about the program, contact its author, Steve Borgatti, at steve@analytictech.com . NetDraw is a program for drawing networks. It uses (or will use) several different algorithms for laying out nodes in 2-dimensional space (3D will come later). Netdraw reads UCINET system files, UCINET DL text files, and Pajek text files (.net, .clu and .vec). JoSS: Journal of Social Structure.
Ulrik Brandes2 Jörg Raab3 Dorothea Wagner4 Abstract: We propose a novel visualization approach that facilitates graphical exploration and communication of relative actor status in social networks.
The main idea is to map, in a drawing of the entire network, actor status scores to vertical coordinates. The resulting problem of determining horizontal positions of actors and routing of connecting lines such that the overall layout is readable is algorithmically difficult, yet well-studied in the literature on graph drawing. We outline a customized approach. The advantages of our method are illustrated in a study of policy making structures from the privatization processes of former East German industrial conglomerates, in which the visual approach led to additional findings that are unlikely to have been revealed using non-visual means of analysis.
