Briefly describe what data visualization is.

"Data visualization is a scientific and technological 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. This is an evolving concept, and its scope is constantly expanding. Mainly refers to the more advanced technical methods, and these technical methods allow the use of graphics, image processing, computer vision and user interface, through the expression, modeling and display of entities, surfaces, attributes and animations, to intuitively explain data.

Development trend Now there are also domestic companies taking this route. Domestic robot software Hightopo is one of them.

In academic circles, there are more and more visual journals now. Pacific vis in Asia, transitional vis in North America and Europ Vis in Europe. These are ordinary journals, not top journals. The application of visualization in academic circles has almost become a bright light. At present, the data generated by anyone who does research is several GB, and tools and specialized personnel are needed to make a visualization to understand these data. Moreover, many second-rate scientific research articles can be submitted to visual first-class journals.

Visualization is not an independent discipline, but a deeper extension of some disciplines such as computer graphics and statistics. For example, the map of social network is applied to many edge algorithms of graphics. Of course, it is most closely related to data mining, because the former is to provide data for the latter, and the latter is to better display data.

Data visualization can not be separated from data mining, and the focus that the visualization author wants to express is directly related to the communication effect of visualization. In other words, when the characteristics and laws of the data itself are not obvious, you need to do a lot of tests and research to find out the laws of the data, and then you can convey the correct and regular visual mode.

Take a simple visualization case of large-scale wind power generation in Hightop, and maybe everyone can understand the visualization data.

Relying on big data technology and overall data mining analysis of large-scale wind turbines, a remote centralized monitoring system for wind turbines is formed. In the visual interface, we can see the monitoring of the environment by the fan, the real-time data of the wind speed and direction at the scene, and the specific situation of the equipment operation. And provide detailed statistical parameters, such as annual power generation, total power, load rate and other data, which can flexibly meet the personalized customization needs of users, thus realizing the intelligent management and control of wind farms by managers.

From the main panel, you can view the fans in wireframe mode. You can click freely to view the running status of each component system and carry out intelligent operation and maintenance in the whole life cycle. Monitor the health status of the fan in time, intelligently diagnose the fan fault and give an early warning. The regular physical examination service will effectively reduce the failure and maintenance costs of fans.

For power plants, monitoring various parameters in the production process is undoubtedly a necessary means to ensure safe and efficient operation. Here, the power generation process of the whole wind turbine is displayed intuitively, and all kinds of data in the monitoring process are docked and converted into operable programs. Comprehensive monitoring of process flow to ensure safe production in power plant.

More information Hightopo is a 2D and 3D graphical interface development framework of Web front-end based on HTML5 standard technology independently developed by Xiamen Top Software Technology Co., Ltd. ... It is very suitable for the interface presentation of real-time monitoring systems and is widely used in telecommunication network topology and equipment management, as well as industrial automation (HMI/SCADA) fields such as electricity and gas. Hajto wave. A unique WebGL layer abstraction is provided, which extends the design model of model-model-view-presenter (MVP) to the field of 3D graphics. With Hightopo, you can focus more on business logic functions, instead of focusing on non-business core technical details such as complex 3D rendering and mathematics.
