Basic concepts

1. What is data visualization

The series of methods used to present relatively complex and abstract data in a more understandable form through visual means is called data visualization. Data visualization aims to more vividly express the inherent information and laws of data, and promote the dissemination and application of data information.

With the support of current new technologies, data visualization can not only be "visual", but also have the characteristics of being communicative and interactive The essence of data visualization is the mapping from data space to graphic space, which is a concrete expression of abstract data

2. What is Big Screen Data Visualization

Big screen data visualization is a data visualization design that uses large screens as the main display medium.

Large area, cool dynamic effects, and rich colors, the large screen is easy to leave a shocking impression on the appearance, creating a unique atmosphere and creating a sense of ceremony. The dual 11 categories of e-commerce screens utilize this feature to create a warm and festive atmosphere. Once invisible data is visualized, it can mobilize people's emotions, evoke resonance, and convey corporate culture and values.

By utilizing the characteristics of large area and the ability to display a large amount of information, sharing key information on a large screen can facilitate team discussions and decision-making. Therefore, large screens are also commonly used for data analysis and monitoring. At present, the visualization of large screen data mainly includes three categories: information display, data analysis, and monitoring and warning.

3. Development of Data Visualization

After obtaining the development of computer graphics, it went through three stages: scientific visualization, information visualization, and data visualization. Initially, scientific researchers proposed the requirements for scientific modeling and data visualization. After entering the 1990s, there was a large demand for single machine data visualization, with EXCEL being a representative of this period. Various products emerged in the Internet era, and big data exploded in growth, Promoting the rapid development of data visualization technology

4. Expression of data big screen

A large screen reflects business and management through the display of data and charts. For example, the theme of a large screen for energy consumption should be: carbon peak, carbon neutrality, reflecting and predicting when carbon peak will occur, how high the peak will be, and the peak situation in various industries and regions; The big screen of state-owned asset supervision should be: expressing the legality and compliance of state-owned asset supervision, preserving and increasing value, reflecting the investment situation of the administrative management, investment intensity, financial budget, financial settlement situation, debt risk situation, property rights registration, transaction situation, state-owned enterprise portrait, policy implementation, enterprise project approval, leader supervision, and supervision in various aspects such as "three major and one major"
