The paper proposes a technology for exploratory visual analysis of heterogeneous data based on the application of various visualization metaphors. It describes the peculiarities of the data under study and the practical problems that arise in their analysis. This paper considers the possibilities of two previously proposed visualization metaphors that form the basis of the technology. The technology’s general scheme is presented and described. A software tool has been developed to implement this technology, enabling the calculation and export of quantitative characteristics of a visual model. This technology was tested for exploratory analysis of experimental data associated with conducting unmanned aerial vehicle flights. The results confirm the feasibility of using this technology and its software tool for real tasks of visual data analysis. Several directions for the further development of the proposed technology and its supporting software tool are formulated.
