Design And Implemention Of Big Data Visualization Layout And Display System

Big data,as another technological innovation after the hot areas such as cloud computing,has continuously promoted all walks of life to optimize the allocation of resources and create cross-border innovation.The significance of massive data research lies in the specialized treatment through technical means,mining its implied value.Data visualization is an important part of the data processing flow.Different forms of visual components transform the inherent laws of data into intuitive external manifestations,which is an important means of analyzing the value of data.Data visualization is an important branch of big data technology.In the current data visualization analysis and display system,the data source structure is not well abstracted,the code reuse degree is low,and the rendering efficiency of the visual component at the front end is not enough.These issues lead to components with the same data dimensions to be processed based on different data formats,without the formation of a uniform standard that can not be used to advance production applications.And due to the absence of a common set of technical architecture and analysis components,the development of visualization is inefficient and the performance of visual page rendering is poor.Based on this situation,this paper presents a complete program of data visualization from several core aspects,such as the big data visualization and display system architecture,visual component library,visual page rendering template engine and visual data engine.The system designed and implemented in this paper implements the adaptability of heterogeneous data sources to the outside world and greatly improves the system compatibility.The DVDL,a data visualization description language,is creatively developed and the visualization view can be rapidly constructed through configuration to greatly improve the project efficiency.The newly designed Visual Rendering Engine DV-PageRenderEngine,a combination of MVVM framework and visualization chart library,dramatically improves page rendering efficiency.Overall,the Big Data visualization and display system reduces the development cost of visual analysis,enhances the user experience of visual analysis,has good practical significance and a large number of application scenarios,and provides an important basis and approach for the value conversion of big data.
