The VISualization & graphIX (VISIX) group led by Prof. Dr.-Ing. Lars Linsen is concerned with the development of interactive visual representations and analysis systems. Today, digital data are acquired with an increasing amount in all fields of science and technology. Visualization methods allow for the extraction of relevant information from these sets of data and to display this information in an effective and intuitive way for human beings. Interaction mechanisms are employed to filter and refine the displays within a visual analysis process. VISIX develops visualization approaches for application in  medicine, life sciences, physics, and geosciences, among others.
