Interaktive Visualisierungen in flussdiagrammbasierten Programmierumgebungen

The analysis and processing of large amounts of data is a current challenge that domain experts as well as amateurs have to face. A possibility established for beginners and experts are flow based programming environments, which allow an user creating a pipeline for calculation. In existing solutions this pipeline is acyclical, which can limit the possibilities of interactive visualizations. In this thesis we want to create a prototypical concept which can weaken these limits. Thus it is possible to implement Brushing and Linking through the physical connection of visualizations and improve the possibilities of visual interaction. A qualitative evaluation shows that these interactions can make a contribution to data analysis. Moreover this evaluation shows that cycles seems to be an intuitive solution for creating a Brushing and Linking setup. In this thesis we discuss existing solutions, the concept and the implementation of a prototype. Concluding we evaluate the prototype and point out some limitations
