Big Data Visualization Implementation Under The Cloud Platform

Today is the era of big data.A large amount of data is generated at all times.These data are valuable but also complex and disorderly.In order to be able to effectively use these massive data,people urgently need a product to help.They analyze and understand these massive and disordered data so that they can make decisions.The 2020 epidemic has made this demand surge.Data visualization can quickly and intuitively display the beauty of data,make the audience's memory lasting,and can transmit and communicate information clearly and effectively through graphical means.People can see the problems behind the data and know the next decision.These characteristics are perfectly in line with The above requirements are met.From this we can see the urgency and necessity of developing a data visualization product.This thesis aims to realize a large-screen data visualization product,and studies big data,data science,visualization,and web-related technologies to ensure that the basic functions of the product can be implemented based on the browser.Analyzed the relevant requirements from the perspective of user use,and divided the data visualization product into five modules: resource management module,presentation module,chart editing module,project management module,and record management module.Designed and implemented a resource management module,and provided it to managers to better manage project users and project resources.A demonstration module is designed and implemented,so that users can view the construction effect at any time during the process of building a large screen,and can demonstrate the large screen that has been built and uploaded to the cloud at any time.Research on data visualization technology,build a page for large screen construction,design and implement a chart editing module,and provide users with the ability to freely construct an ideal large screen.The project management module is designed and implemented,so that users can process the large screen after constructing it,including download function,release function and preview function.Designed and implemented a record management module,providing users with a fallback function when building large screens,allowing users to build with confidence and boldness.Finally,the above functional modules are integrated,and the front-end page is designed as a single-page application to enhance the developer's development experience,and realize a data visualization large-screen product,so that users no longer have to worry about facing massive and disordered data.Finally,functional testing,performance testing and reliability testing of data visualization products are carried out.The test results show that large-screen data visualization products can meet the basic requirements of graphical data display,and the user has a good construction experience.
