Scalable resolution display environments, including immersive data observatories, are emerging as equitable and socially engaging platforms for collaborative data exploration and decision making. These environments require specialized middleware to drive them, but, due to various limitations, there is still a gap in frameworks capable of scalable rendering of data visualizations. To overcome these limitations, we introduce a new modular open-source middleware, the Open Visualization Environment (OVE). This framework uses web technologies to provide an ecosystem for visualizing data using web browsers that span hundreds of displays. In this paper, we discuss the key design features and architecture of our framework as well as its limitations. This is followed by an extensive study on performance and scalability, which validates its design and compares it to the popular SAGE2 middleware. We show how our framework solves three key limitations in SAGE2. Thereafter, we present two of our projects that used OVE and show how it can extend SAGE2 to overcome limitations and simplify the user experience for common data visualization use-cases.

开放式可视化环境(OVE):用于可扩展地呈现数据可视化的Web框架

可扩展的分辨率显示环境,包括沉浸式数据观测站,正在成为公平的,具有社会参与性的平台,用于协作数据探索和决策。这些环境需要专用的中间件来驱动它们,但是由于各种限制,在能够进行数据可视化的可伸缩呈现的框架中仍然存在差距。为了克服这些限制,我们引入了一种新的模块化开源中间件,即开放可视化环境(OVE)。该框架使用Web技术来提供一个生态系统,以使用跨越数百个显示器的Web浏览器来可视化数据。在本文中,我们讨论了框架的主要设计功能和架构及其局限性。接下来是对性能和可扩展性的广泛研究,它可以验证其设计并将其与流行的SAGE2中间件进行比较。我们展示了我们的框架如何解决SAGE2中的三个关键限制。此后,我们介绍两个使用OVE的项目,并展示它如何扩展SAGE2以克服限制并简化常见数据可视化用例的用户体验。
