**8. Conclusion**

The issue of finding the sources arouses a whole range of questions. First, an assessment of metaphor applicability is necessary both for the given applications and for a specific task. When assessing the applicability of a metaphor, one should evaluate the way this metaphor can depict the features of a certain application, for which the visualization system is built. However, imaging precision does not necessarily guarantee success for the system. For example, a brain metaphor, precisely depicting the work of a parallel program, is not very convenient in terms of perception, which strongly hampers visualization perception. Magic features are useful in addition to the complex of computer metaphors but are not sufficient. There are examples when a metaphor, for various reasons, was not successful even after introducing these features. Gamification is an interesting idea. However, the question remains whether game components risk distracting the user from their intellectual activity by putting them into a silly, playful mood. Distraction from the main task may also be caused by the magic features of metaphors, especially in environments based on virtual reality. When using virtual reality, one should also analyze the potential user states in terms of increasing or decreasing performance. All these thoughts show that research of substantial user groups is necessary. It is worth noting that in case of software visualization, this research is relevant, as there is a considerable number of tasks and a significant number of experts.
