    Treemap is a visualization method for hierarchical structures in which nodes are drawn as rectangles and arranged in a nested style. Several variations of Treemap have been developed to represent different types of data. In this paper, we propose an Edge Equalized Treemap, a representation that embeds visual data such as a bar chart in leaf rectangles. This representation is characterized by leaf ...

    Visualization of discussions is an intensively explored information visualization area. Many existing approaches explore the discussions from the point of view of individual participants, often omitting interesting information about the discussion itself. We present a visualization technique that centers around the discussion, its dynamics, intensity and topic changes. The flow of the text is divi... View full abstract»

    Fast computation of two-dimensional layouts of hierarchically clustered networks is a well-studied problem in graph visualization. We present algorithmic and experimental advances on the subject: (i) We propose a new drawing algorithm that combines space-filling and fast force-directed methods; it runs in O(nlogn+m) time, where n and m are the number of vertices and edges of the network, respectiv...

    The constant growth of available genealogical information has encouraged the research of visualization techniques capable of representing the corresponding large amount of data. An H-Tree Layout has been recently proposed to represent pedigree data as a way to overcome some of the limitations of traditional representations. However, this new method has its own limitations which may hinder its adop... View full abstract»

    The usage of visualizations to aid the analysis of time oriented data plays an important role in various fields of applications. The need to visualize such data was decisive for the development of different visualization techniques over the last years. One of the frequently applied techniques is animation in order to illustrate the movements in such a way to make changes in the data transparent. H... View full abstract»

    Nowadays component applications can easily consist of hundreds or thousands of components and it is thus difficult to understand their structure. Diagram visualisation does not help much because of visual clutter caused by big amount of elements and connections, especially in the case of flat component models. This paper describes a novel approach of removing a large part of connections from the d... View full abstract»

    In this paper, we report two methods to visualize migration of people in an artificial society. The artificial society system we target have been developed for simulating demographic changes in prehistoric and protohistoric periods in Japan. The system is capable of long term simulation of demographic changes in and migration between areas. We visualize migration from two perspectives: global view... View full abstract»

    Pattern discovery plays an important part in the graph analysis process. Good examples are the detection of communities in social networks or the clustering into pathways of metabolic networks. However, elements may be shared by several clusters, making the patterns entangled. When mining such data, experts are usually interested in both each individual cluster and their overlaps. Dedicated visual... View full abstract»

  • AIVA vs UML: Comparison of Component Application Visualizations in a Case-study

    UML is the state of the art in visualization of software. However, it does not satisfy the needs of modeling in the domain of component applications and complex software architectures. UML has to be extended with profiles so as to be able to model the specifics of a particular component model; its diagrams are not scalable, therefore one has to balance the amount of information and readability; an...

    Many efforts from both artists and scientists on color design have resulted in a variety of models and rules devoted to coloring graphics. Based on these results, a lot of interactive tools are now available to help with color design based on various sorts of color themes, templates, palettes, swatches, brushes, etc. However, despite the numbers of tools and results available, in many situations, ...

    This paper presents a novel vertical timeline information-visualization technique developed to support the analysis of human-computer dialogue data. The technique uses combined linked views including distorted views to effectively communicate the timing of dialogue events while presenting text in such a manner that it is easily readable. A prototype has been implemented and tested to demonstrate t... View full abstract»

    Space-filling visualization techniques have proved their capability in visualizing large hierarchical structured data. However, most existing techniques restrict their partitioning process in vertical and horizontal direction only, which cause problem with identifying hierarchical structures. This paper presents a new space-filling method named Angular Treemaps that relax the constraint of the rec... View full abstract»

    A gene network is constructed with genes as nodes, and interactions between genes as edges so as to reveal unknown gene functions and relationship. However, nodes and edges of gene networks are usually very numerous. Because of that, it may be difficult to understand relations between genomic functions and gene-gene interactions, if it is visualized by traditional techniques. This paper presents o...

    We present an approach based on a forest metaphor to ease the comprehension of evolving object oriented software systems. The approach takes advantages of familiar concepts such as forests of trees, sub-forest of trees, trunks, branches, leaves, and color of the leaves. In particular, each release of a software is represented as a forest that users (or software maintainers) can navigate and intera... View full abstract»
