In this work, is described and developed a tool for visualisation of engineering information evolution during product development. After a short description of traceability of engineering information evolution, main goals of the visualisation tool are described. Next, a variant of the force directed graph layout algorithm and Barnes-Hut algorithm are described it is explained how these algorithms were used in visualising the evolution of complex networks. After that, fast algorithm for detecting community structure in networks, and using force-directed layout algorithm in visualising community structure are described. In the end, a short review of several graph visualisation toolkits is given, and results obtained by using the visualisation tool that has been developed for two complex networks are shown.
