Dynamic Graph Drawing in Visone

In early 2008 a new testing branch of the network analysis software visone has been made publicly available [Baur et al., 2008]. This realease includes the ability to process dynamic networks. A central feature is a dedicated dynamic layout algorithm which we present here from a methological and application oriented point of view. We first describe this algorithm from an algorithmic perspective. More precisely we show how the local majorant method of the related layout algorithm given by Kamada and Kawai can be adapted to layout dynamic networks. Following the methodological part we also address some problems and some other features of our implementation. Given the information in this document users of the dynamic layout procedure in visone should be able to employ the various available options efficiently to get the desired results.
