  abstract  = {We describe an approach to visually analyzing the dynamic behavior
              of 3D time-dependent flow fields by considering the behavior of the
              path lines. At selected positions in the 4D space-time domain, we
              compute a number of local and global properties of path lines describing
              relevant features of them. The resulting multivariate data set is
              analyzed by applying state-of-the-art information visualization approaches
              in the sense of a set of linked views (scatter plots, parallel coordinates,
              etc.) with interactive brushing and focus+context visualization.
              The selected path lines with certain properties are integrated and
              visualized as colored 3D curves. This approach allows an interactive
              exploration of intricate 4D flow structures. We apply our method
              to a number of flow data sets and describe how path line attributes
              are used for describing characteristic features of these flows.},
