Semiotic Assessment of Visualization Tools Alena Zakharova 1, Aleksey Shklyar 2 and Evgeniya Vekhter 2 1 Institute of Control Sciences of Russian Academy of Sciences, 65, Profsoyuznaya st., Moscow, 117997, Russian Federation 2 Tomsk Polytechnic University, 30, Lenin Ave., Tomsk, 634050, Russian Federation Abstract A visual analytics means is a set of tools used to obtain a visual representation of the data explored by the user, its interpretation and complete analysis. It is quite possible that such a set will be a developed specialized environment for continuous user interaction with a data stream, which has the capacity to control and replace the way of visual data representation. A wide range of existing visualization tools, as well as unlimited borrowing of technological solutions originally intended for a narrow application area, and the transfer of the capabilities they create to other directions make it urgent to form a sound approach to the comparison and selection of means of data visual representation of a given complexity [1]. The purpose of this selection is to save the end user’s resources, based on the absence or minimization of resource losses arising at the stage of selection and testing of visual analytics tools. The paper shows the possibility of using a semiotic visualization model for purposeful design or selection of visualization tools.
