【摘要】：随着信息时代的到来,越来越多的信息资源变得触手可及,人们在生产、生活当中也产生了海量的数据,因此信息在爆炸式增长。在数据分析的各种方法中,数据可视化是一种极其重要的策略。数据可视化以直观的方式展示数据及其结构关系,更有效地传递了信息,进而辅助人们进行决策。基于上述观察,本文对数据可视化技术进行了深入的研究,提出并实现了数据可视化系统,以快速生成用户自定义样式的交互式图表。本文提出并解决了数据可视化技术中两大技术难题:一是系统如何将数据转换为可交互的图表来呈现给用户,并且用户如何达到个性化定制图表样式的目的。二是用户如何描述期望的交互操作,以及系统如何将交互操作产生结果反馈给用户。针对数据的可视化呈现难题,本文基于图形语法描述了图表结构,构建生成了图表视图。同时,本文提出了主题模型以满足用户对图表的高度定制化需求。针对用户交互的难题,本文提出了声明式交互语法,此语法使用类似自然语言的描述方式以声明用户的交互操作。在交互技术的实现方面,本文提出了事件流模型,对发生在图表中的各种事件进行建模。同时,本文实现了事件处理模型以解析用户的交互操作,将交互结果反馈给用户。本文实现的数据可视化系统,作为网易敏捷商业智能平台的子系统,在图表的可交互性和个性化定制这两方面得到了充分地检验,为探索数据的规律与意义奠定了良好的基础。
[Abstract]:With the arrival of the information age, more and more information resources become within reach, people in production, life has also produced a huge amount of data, so information in the explosive growth. Among the methods of data analysis, data visualization is an extremely important strategy. Data visualization displays data and its structure in an intuitive way, which can transfer information more effectively and help people to make decisions. Based on the above observations, the data visualization technology is deeply studied in this paper, and a data visualization system is proposed and implemented to quickly generate user-defined interactive charts. In this paper, two technical problems in data visualization are proposed and solved: one is how the system transforms data into interactive charts and presents them to users, and how the users achieve the purpose of customizing the chart style. The second is how the user describes the desired interactive operation and how the system feedback the result of the interactive operation to the user. Aiming at the difficult problem of visualization of data, this paper describes the chart structure based on graph syntax, and builds the chart view. At the same time, the theme model is proposed to meet the highly customized needs of users. To solve the problem of user interaction, this paper proposes a declarative interaction syntax, which uses a natural language-like description to declare a user's interaction. In the aspect of the implementation of interaction technology, the event flow model is proposed, and the events occurring in the diagram are modeled. At the same time, the event handling model is implemented to parse the interactive operation of the user and feedback the interactive result to the user. As a subsystem of NetEase agile business intelligence platform, the data visualization system realized in this paper has been fully tested in the two aspects of graph interactivity and personalized customization, which has laid a good foundation for exploring the rules and significance of data.
