                         science and engineering applications, raising the need for robust 
                         methods to capture and represent the global vector field behavior. 
                         One such representation, the topological graph, partitions the 
                         domain into regions where the flow of the vector field is 
                         homogeneous. This work introduces a topological graph construction 
                         based on streamlines. It is guaranteed to produce a coherent 
                         result even when some singularities are not detected. This work 
                         also details an application of topological graphs to improve the 
                         generation of self-animated images. In this application, the 
                         streamline-based approach carries almost no overhead, since 
                         self-animated images already rely on streamlines, but leads to a 
                         threefold speed-up of the core processing.",
