In the era of big data, the rapid development of information technology has made the sharing of data and information more free, bringing convenience to the public, but at the same time, the massive amount of data also brings “information anxiety.” In this paper, we use the knowledge of design discipline, combined with psychological cognitive science, statistics, and communication discipline, and ... [Show full abstract] analyze a large number of excellent cases to effectively combine “information visualization-visual representation-design.” The purpose of this study is to enable audiences to efficiently access information through visual symbols in a large amount of data and to increase their interest in reading and satisfaction in accessing information. As a carrier of communication between designers and audiences in the process of visual representation of information visualization, visual symbols can effectively convey information content and emotional concepts to audiences. Finally, based on the theoretical support of the previous paper, combined with our own practical experience, we conduct a systematic study on the application of design thinking and the construction of design methods for the design of visual representations of information visualization. A comparative study on the aesthetics of different categories of APP interface design is conducted, and it is believed that different categories of APP can create distinctive and different categories of APP interface aesthetics through the differentiated design of interface layout, content expression, and visual form, which is considered as the ultimate goal that APP interface design must pursue. Visual representation is a method and means to realize information visualization as a representation practice that expresses the meaning of information in the form of visual symbols. The visual representation of information visualization uses visual symbols as a medium, and the audience interprets the visual symbols based on cognitive experience to obtain information, which helps to maximize the dissemination of information.
In the context of the “big data era,” big data, supported by mobile Internet and information technology, has been widely used in many fields and has become one of the core resources affecting social development. The sharing of data and information is becoming increasingly flexible and diverse, and information is becoming globalized . Faced with the language communication barriers between different ethnic groups and cultures, a communication method that allows information to flow freely is needed to facilitate communication between various groups and cultural exchanges between different countries . In recent years, the number of people and web pages on the Internet has been on the rise, and the amount of data and information has been increasing, but there is a lot of information but it is complicated and disorganized, people have to passively receive thousands of pieces of information every day, and too much data will easily cause “information anxiety.” Under the double pressure of information explosion and fast-paced life, people tend to read in fragments, and the mode of reading is changed from text to map, and the purpose of reading information is also clearer . However, nowadays, the means of information processing obviously cannot keep up with the speed of information growth, and the traditional way of information dissemination can no longer meet the needs of the public and the continuous development of society, so how to quickly obtain valuable information from the massive amount of information has become the focus of most people’s attention . The main problem facing information disseminators is how to quickly catch audience’s attention, effectively disseminate information, reduce the visual pressure of the audience, eliminate visual barriers, and make the information receiver quickly and actively obtain information. The current design forms for information dissemination focus too much on the design symbols, ignoring the psychological needs of the audience and the information dissemination process, resulting in the failure to maximize the dissemination of information .
Information visualization visual representation communication design uses visual symbols as a mediator, giving the designer the dual identity of information designer and visual designer to communicate information, which is more in line with today’s needs . Visual communication design is a process in which a designer conveys a specific message to the communicated object through a visible form of artistic expression in order to achieve the desired purpose, thus having a certain influence on the communicated object. Visual communication design is composed of three main elements: text, illustration, logo and other visual symbols, communication, and design. Visual communication design is divided into several parts according to design science, such as type design, display design, packaging design, and logo design . Visual communication design has been developed from the western graphic design (graphic design), and the development of technology has brought people new visual experience, and visual communication design has emerged accordingly. Visual communication design started relatively late in China, but with the rapid development of China’s economy in recent years, the huge demand of the market has stimulated the rapid development of visual communication design teaching . The goal of visual communication design teaching is more accurate, the design of teaching courses and contents is more perfect, and the investment in teaching facilities is constantly strengthened, in order to cultivate more qualified visual communication design talents for the society. The teaching of visual communication design in China, from a new starting point, can better meet the market requirements and develop in a clearer direction by combining with new science and technology . Therefore, at present, China’s visual communication design teaching must seize the opportunity to promote its own rapid and healthy development with new design concepts and the application of new technologies combined with the needs of social development. As an important content of design teaching, visual communication design has been developing rapidly in China in recent years, and it is constantly updated in terms of teaching philosophy, teaching methods and teaching equipment, actively combining with other majors and insisting on the long-term development path of diversification and modernization . Digital technology, as a new way of artistic expression, has prompted visual communication design to enter a new stage of development. The maturity of digital technology makes the digital expression of visual communication design a new trend in the field of visual communication design. The digitalization of visual communication design has prompted designers to design through multidisciplinary cross-thinking and multiple design methods, and design strategies and thinking are constantly evolving . Through digital technology and media, it can not only enrich designers’ expressions and provide diversity of artistic expressions but also enhance the participation and interaction of information receivers and improve the effectiveness of information communication, as well as promote flexible and broader choices of communication methods.
In the context of an increasingly digital living environment, digitalization has become an important part of popular culture, and the interactive development of visual communication design from static to dynamic makes it a digital art with its own uniqueness. The digital expression of traditional visual design reflects the infinite charm of combining art and technology and represents the new development direction and trend of future design art. In this paper, we clarify the concepts of information visualization and visual representation and discuss the communication mechanism between information visualization, visual representation, and visual communication based on Michel’s “quadrilateral representation system theory” and Stuart Hall’s “encoding and decoding” theory. Secondly, visual symbols, as a carrier of communication between designers and audiences in the process of visual representation of information visualization, can effectively convey information content and emotional concepts to audiences. In addition, the application principles, application forms and shapes, and types of application of visual representation of information visualization are studied with typical cases; finally, based on the theoretical support of the previous paper, combined with its own practical experience, the design of visual representation of information visualization is systematically studied in terms of design thinking application and design method construction. On the basis of the research results of this paper, based on the analysis of the online questionnaire report, the visual representation design of information visualization is carried out to disseminate health protection information based on “health protection knowledge,” which is of public concern, to verify the feasibility of the previous research.

Any form of artistic expression is created on the basis of social and technological development, and technology can promote the development of art . Digitalization is the basis of computer, multimedia, Internet, and information society technology. The arrival of the digital era has brought new forms of artistic expression to social life, and the widespread use of digital media has also changed the way people receive and disseminate information. The development of digital technology has also brought changes to visual communication design in terms of design methods and processes, and visual communication design based on digital expression has characteristics such as rich information content, comprehensiveness, and interactivity . Visual communication design in the digital era adopts various forms of information expression such as sound, graphics, and text and adopts a lot of computer and multimedia technology, such as Photoshop and other graphic processing software, and the design works can realize the interactive communication between the sender and the receiver . At the same time, the medium of communication has also expanded from traditional books, newspapers, and TV to mobile phone MMS, mobile phone newspapers, and digital media such as network advertising and electronic display. The design software can be used to create interactive communication between senders and receivers.
The digital visual communication design process also has new characteristics, from the basic design definition by the designer according to the design purpose and the basic information to be expressed, to the determination of the information content to establish the overall information architecture, to the selection of suitable expressions according to the information using digital technology for digital processing design, and finally, to the combination of the corresponding software and hardware equipment to communicate the design results through digital media. Digitalization puts forward new goals for the teaching of visual communication design, requiring the cultivation of visual communication design talents who use digital expression as the main means of expression as the fundamental goal, and the cultivation of students’ innovative consciousness and digital concepts . At the same time, digitalization also puts forward new requirements on the concept, content, and method of teaching visual communication design, and digitalization inadvertently introduces the “diversity” of expression and “individualization” of communication content into the teaching of visual communication design.
First of all, digital expression makes the scope of teaching visual communication design more extensive, so that it extends from traditional graphic design, industrial design, product design, etc. to the scope of computer networks, with stronger professionalism. The teaching of visual communication design should not only focus on the traditional theoretical teaching and professional basic education but also on the application and operation of digital technology. Secondly, from the point of view of teaching methods, the traditional teacher-led lecture method has been difficult to adapt to the requirements of the digital era, based on digital visual communication design teaching must be combined with teaching and practical operation, and focus on the cultivation of students’ hands-on ability on the basis of theory, so it should take more emotional experience, case teaching, and problem teaching methods, through the interaction between teachers and students and students and society, and make full use of multimedia, the Internet, and other digital technology . Therefore, we should adopt more methods such as emotional experience, case teaching, and problem teaching, through the interaction between teachers and students and students and society, make full use of multimedia, Internet, and other digital technologies for teaching services, and improve the effect of visual communication design teaching through effective methods and advanced auxiliary equipment . At the same time, we should also pay attention to the graduation design of students should be closely related to the needs of the times and try to improve students’ ability to use various kinds of knowledge comprehensively, so as to achieve the effect of comprehensive development of theory and practical ability.
In order to adapt to the digitalization of visual communication design, we should pay attention to cultivating students’ understanding and mastery of visual language, their unique understanding of design language from an artistic point of view, and their ability to use it flexibly and skillfully, as well as cultivating students’ practical operation and visual expression ability, so that they can master digital technology and use digital hardware and software for artistic design. Visual communication design, as a branch of art and design, must be based on art . Therefore, the teaching of visual communication design must pay attention to the teaching of professional foundation courses, actively study the curriculum design and teaching methods of foreign visual design teaching, integrate and reconstruct the basic design courses, strengthen theoretical teaching, and lay a solid professional foundation for art design . Although the digitalization of visual communication design is very technical, the basic courses are the basic guarantee for design, and we still need to pay attention to the teaching of professional basic courses such as sketching, design color, and type design. At the same time, the digitalization of visual communication design is a modern art design supported by technology, with strong practicality, and its use must be closely integrated with modern digital technology and digital media . Therefore, the teaching of visual communication design should pay attention to the cultivation of students’ technical operation ability and improve their comprehensive design ability while focusing on the teaching of art foundation . Especially in the current context of numerous digital media and complex hardware and software devices, the teaching of visual communication design must strengthen students’ ability to use computer, Internet, and multimedia technologies for artistic design and master the methods and skills of using common design software and hardware devices.

3.1. Visual Visualization Theory
Cognition, the process by which people acquire knowledge, apply knowledge, or process information, is the most basic human mental process. It includes sensation, perception, memory, thinking, imagination, and language. According to Bruner, a pioneer of cognitive psychology, cognitive representation is the process by which an individual perceptually converts objects or events in his or her external environment into internal mental events. In this paper, the theories of visual cognitive representation in information visualization have been studied, including “inner picture theory,” “natural association theory,” “custom theory,” “memory principle,” “memory theory,” “memory principle,” and “emotional design principle.” Visual flow refers to the natural visual flow habit of people when they read, usually from top to bottom, left to right, and clockwise from top left to bottom right. Indicative visual symbols will guide the viewer to read according to the visual order and enhance the fluency and interest of reading. The audience can understand the process of soft drink manufacturing more clearly and intuitively. Visual misperception means that when an observer observes an object, based on empiricism or under the interference of objective factors, he or she makes a wrong judgment and perception of the object that is not in line with the objective facts. The German psychologist Hermann Ebbinghaus used circles of the same size placed around two groups of circles of different sizes to produce the misperception effect that the left and right sizes of the central circle were different (as in Figure 1), revealing the phenomenon that the brain incorrectly parses visual information.
