In this paper I describe JUST a software framework designed to help researchers rapidly
develop custom simulation models of networks. JUST stands for JUNG Universal
Simulation Toolkit. JUNG is an open-source project written in Java that focuses on network
analysis (O’Madadhain et al. 2010). JUST is not just a framework to develop and run
simulations, but a complete package that gives users the ability to visualize their models,
share them with others and export the data they generate to other packages for analysis (see
images of the software in Illustrations 1 and 2).
