But no mechanism is provided to really interact with the application data (semantic interaction) that has been changed step by step by the process of visualization.In this paper general concepts are elaborated and presented to achieve semantic interaction in dataflow environments for Scientific Visualization.10.1111/1467-8659.1130139139-151
