    Static or dynamic graphs are typically visualized by either node-link diagrams, adjacency matrices, adjacency lists, orhybrids thereof. In particular, for the case of a changing graphstructure a viewer wishes to be able to visually compare thegraphs in a sequence. Doing such a comparison task rapidlyand reliably can give support to visually analyze the dynamicgraph for certain dynamic patterns. In... View full abstract»

    People flow information brings us useful knowledge in various industrial and social fields including traffic, disaster prevention and marketing. However, it is still an open problem to develop effective people flow analysis techniques. We suppose compression and data mining techniques are especially important for analysis and visualization of large-scale people flow datasets. This paper presents a... View full abstract»

  • Adaptive Blending of Multiple Network Layouts for Overlap-Free Labeling

    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (1381 KB) | HTML iconHTML

    Conventional force-directed algorithms are known as a common approach to aesthetically drawing networks while they still suffer from self-overlaps especially when the network nodes are annotated with text labels. Incorporating space partitioning techniques including Voronoi tessellation are often effective to spare enough space around each node while this may incur different artifacts such as unex...

  • Tree Visualizations in Structured Data Recursively Defined by the Aleph Data Relation

    In visualization, tree structures and parent/child data relations are basic. In an earlier article, the author demonstrated how a single tree structure emerged from relational data by recursion, and by the properties of the underlying strings of 0's and 1's of its data symbols. The paper takes a closer look at the components of this visualization to investigate this transformation in greater detai... View full abstract»

    Artificial Intelligence (AI) has infiltrated almost every scientific and social endeavour, including everything from medical research to the sociology of crowd control. But the foundation of AI continues to be based on digital representations of knowledge, and computational reasoning therewith. Because so much of modern knowledge infrastructure and social behaviour is connected to AI, understandin... View full abstract»

  • Design Tool of Color Schemes on the CIELAB Space

    Color plays an important role in information visualization. To use the colors as visual representations of the data effectively, designing color schemes that consider perceptual differences between colors is necessary. We developed a tool to assist in color-scheme design when using the CIE1976L*a*b* (or CIELAB) color space. The developed tool provides functions to assist in designing color schemes...

  • Native Cross-Platform Visualization: A Proof of Concept Based on the Unity3D Game Engine

    Today many different devices and operating systems can be used for InfoVis systems. On the one hand, web-based visualizations can be used to be compatible with several systems, but the performance depends on optimized browser engines. On the other hand, it is possible to build a native system which supports all the benefits for just one device. However, transferring the code to another system mean... View full abstract»

  • Visualizing Uncertainty of Edge Attributes in Node-Link Diagrams

    In this paper, we discuss and evaluate the handling of uncertainty in visual network analysis, i.e. the uncertainty of edge attributes. This can be useful to answer a question like ”How reliable is a flow rate value on a specific edge/pipeline?”. For investigating the most suitable and most intuitive representation of uncertain edge attributes in visual network analysis, we extend the state of the... View full abstract»

  • Enhancing Polymetric Views with Coarse-Grained Views

    MetricAttitude is a visualization approach implemented in an environment that provides a mental picture by viewing an object-oriented software by means of polymetric views of classes (i.e., fine-grained). In this paper, we present an extension of MetricAttitude which visualizes a software by levels considering not only its class view but also its package views in terms of nested packages (i.e., co...

  • Time-Varying Data Visualization Using Clustered Heatmap and Dual Scatterplots

    Heatmap is one of the effective representations for time-varying data visualization. It may require large display spaces when an input dataset contains large number of data items or time steps. We may often want mechanisms to interactively filter non-important data items or time steps, so that we can form appropriate sizes of heatmaps and focus on important data items or time steps.

  • Drawing Clustered Graphs Using Stress Majorization and Force-Directed Placements

    Publication Year: 2016, Page(s):69 - 74
    Request permission for reuse | Click to expandAbstract | PDF file iconPDF (288 KB) | HTML iconHTML

    We propose a novel layout algorithm to draw clustered graphs. Our algorithm applies a stress model to draw intra-cluster graphs and a spring-electrical force model to place clusters. Our strategy modifies the original stress model in graph drawing by integrating the force from the center to push and pull the intra-cluster nodes based on their outside connectivity. We also apply the idea of torque ... View full abstract»
