在本文中，我们提出了使用嵌入标准 HTML 文档中的半引导交互式可视化来交流和呈现所获得知识的新颖方法。这项工作的目标是让分析师（作者）探索数据并同时保存重要的发现，从而能够通过互联网进行协作和分享所获得的见解。该文档的读者将受益于收到一个集成的交互式文档，该文档可以“指导”他们理解和测试假设，从而更快地理解所呈现的视觉信息并提高其置信度。该方法基于视觉分析（VA）工具包（GAV），该工具包还提供了一种机制，通过“记忆的交互式可视化视图”或可在探索性数据分析过程中随时保存的快照来支持分析推理过程中交互式事件的存储。在典型场景中，由 GAV VA 组件组成的应用程序与目标数据和发现快照一起嵌入到 HTML 文档中。任何标准 HTML 事件（例如用户单击文本链接或图像）都可用于实例化快照，从而在描述性文本和交互式可视化演示之间创建链接。由于 GAV 应用程序和相应的数据与驻留在客户端计算机上的 HTML 代码集成，因此可以使用硬件加速图形来提供要求苛刻的可视化的交互性能。我们展示了所开发的方法在地理分析和分子可视化场景中的潜力。
In this paper we present novel means to communicate and present gained knowledge using semi-guided interactive visualizations embedded in standard HTML documents. The goal of the work is to let the analyst (author) explore data and simultaneously save important discoveries and thus enable collaboration and sharing of gained insights over the Internet. The readers of the document will benefit from receiving an integrated and interactive document that can "coach" them in the understanding and testing of hypotheses leading to faster understanding and a higher confidence level in the presented visual information. The approach is based on the visual analytics (VA) toolkit (GAV), which also provides a mechanism that supports the storage of interactive events in an analytical reasoning process through "memorized interactive visualization views" or snapshots that can be saved at any time during an explorative data analysis process. In a typical scenario an application, comprised of GAV VA components, is embedded in the HTML document together with target data and the snapshots of discoveries. Any standard HTML event, such as the user clicking a textual link or an image can be used to instantiate a snapshot, creating a link between a descriptive text and an interactive visualization presentation. As the GAV application and corresponding data are integrated with the HTML code, residing on the client machine, hardware accelerated graphics can be used to provide interactive performance of demanding visualizations. We demonstrate the potential of the developed methods in the context of geoanalytics and molecular visualization scenarios.
