This webinar focused on the design of visualisation software for translational toxicology, with particular reference to the challenges that the many different sources of toxicology data pose. We outlined our work on a visualisation application for the EU project, eTRANSAFE, which aims to build a large software system for investigating translational toxicology. We discussed the challenges in developing a tool which allows users to explore these data concurrently, without intensive transformation of data by the end-user.
