Visualization technologies in world research

Every year the amount of information increases significantly, particularly in education, and at the same time, the possibilities of digital tools utilization for processing it changes. Scientific progress, virtualization and automation of many processes have a beneficial effect on this, and therefore there is a need for their processing and accounting, which entails an increase in computing power and data rates. The continuous flow of information is a necessary condition for the existence of modern civilization and the reason for the overload with information and media activity consciousness, which provoked the emergence of a new type of thinking based on the clip perception of messages. A person from all the variety of information grasps the brightest fragments that appeal to his consciousness and thus forms a chain of levels of information perception "image - title - text - understanding", where the information's visual component acts as a link from one to another and provides information connection. The visual component of information (visualization), based on certain associations, stereotypes of thinking, conveys the essence of significant event, fact, phenomenon, process, important for a person in time and space. Visualization is the most important step in the data analysis process. It helps to present research results in a simple and clear form, often serves as a key factor for decision-making in various fields. Although many people associate digital visualization with linear graphs and tables exclusively, in reality it is a big concept, a system of transmitting complex ideas, patterns and data through visual images. The analysis of the notions "visualization", "information visualization", "graphic image", "graph" is performed in the article. Varieties and methods of digital visualizations by different researchers are analyzed. The methods of digital visualization by Swiss researchers, who presented them in the form of a periodic table, are described. The main types of digital visualizations with examples and their possible application are described in detail.
