“This paper firstly provides a general introduction in the most important aspects and ideas of Visual
Analytics. This multidisciplinary field focuses on the analytical reasoning of typically large and complex
(often heterogeneous) data sets and combines techniques from interactive visualizations with computational
analysis methods. Hereby, intuitive and efficient user interactions are a fundamental component which has
to be efficiently supported by any Visual Analytics system” (from the abstract, Kerren and Schreiberm 2012)
