1: Data visualization is a scientific and technical research on data visualization. Among them, the visual expression of the data is defined as a kind of information extracted in a certain summary form, including various attributes and variables of the corresponding information unit. The main purpose is to convey and exchange information clearly and effectively by means of graphics, and realize the unification of mature scientific visualization field and young information visualization field.
2. Visual charts can display data in a more intuitive way. Make the data more objective and convincing. In all kinds of reports, it is simple and reliable to display data with intuitive charts. Users can conveniently manage and develop data in an interactive way, and can see multiple attributes or variables of data representing objects or events. Data can be classified, sorted, combined and displayed according to their values in each dimension.
3. Big data visualization technology. It can also be displayed by images, curves, two-dimensional graphics, three-dimensional shapes, animations, etc., and its patterns and relationships can be intuitively analyzed. In short, data visualization can greatly speed up data processing and effectively use the massive data generated at all times; It can guide and control the calculation and programming process, change the conditions on which the process is based through interactive means, and observe its influence.
