    Climate research produces a wealth of multivariate data. These data often have a geospatial reference and so it is of interest to show them within their geospatial context. One can consider this configuration as a multi-field visualization problem, where the geo-space provides the expanse of the field. However, there is a limit on the amount of multivariate information that can be fit within a cer... View full abstract»

    Turbulent flows are intrinsic to many processes in science and engineering, and efforts to elucidate the physics of turbulence are of critical importance to many fields. However, ongoing efforts to achieve a fundamental understanding of the mechanisms of turbulent flow are hindered by the difficulty of quantifying the complex, non-linear interactions between individual eddies in these flows. The d... View full abstract»

  • Similarity-based 3-D atmospheric nucleation data visualization and analysis

    Publication Year: 2013, Page(s):137 - 144

    Atmospheric nucleation is a process of phase transformation, which serves a significant role in many atmospheric and technological processes. To simulate atmospheric nucleation activities, certain molecular models with three-dimensional (3-D) structures are generated. Analyzing these 3-D molecular models can help promote understanding of nucleation processes. Unfortunately, the ability to understa... View full abstract»

    The edge, which can encode relational data in graphs and multidimensional data in parallel coordinates plots, is an important visual primitive for encoding data in information visualization research. However, when data become very large, visualizations often suffer from visual clutter as thousands of edges can easily overwhelm the display and obscure underlying patterns. Many edge-bundling techniq... View full abstract»

  • A study of animated transition in similarity-based tiled image layout

    Publication Year: 2013, Page(s):157 - 170
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (5443 KB)

    For many information visualization applications, showing the transition when interacting with the data is critically important as it can help users better perceive the changes and understand the underlying data. In this paper, we investigate the effectiveness of animated transition in a tiled image layout where the spiral arrangement of the images is based on their similarity. Three aspects of ani...

  • ManyInsights: A visual analytics approach to supporting effective insight management

    Publication Year: 2013, Page(s):171 - 181
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (9484 KB)

    Although significant progress has been made towards effective insight discovery in visual analytics systems, there are few effective approaches for managing the large number of insights generated in visual analytics processes. This paper presents ManyInsights, a multidimensional visual analytics prototype that integrates several novel insight management approaches proposed by the authors in their ... View full abstract»

    Microblogging services provide a novel and popular communication scheme for Web users to share information and express opinions by publishing short posts, which usually reflect the users' daily life. We can thus model the users' daily status and interests according to their posts. Because of the high complexity and the large amount of the content of the microblog users' posts, it is necessary to p... View full abstract»

  • An online visualization system for streaming log data of computing clusters

    Publication Year: 2013, Page(s):196 - 205
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (2615 KB)

    Monitoring a computing cluster requires collecting and understanding log data generated at the core, computer, and cluster levels at run time. Visualizing the log data of a computing cluster is a challenging problem due to the complexity of the underlying dataset: it is streaming, hierarchical, heterogeneous, and multi-sourced. This paper presents an integrated visualization system that employs a ... View full abstract»
