In this paper, the gate matrix layout is formulated as a planning problem where a "plan" (the solution steps) is generated to achieve a "goal" (the gate matrix layout) that consists of subgoals interacting each other. Each subgoal corresponds to the placement of a gate to a slot. or to the routing of a net connecting gates. The interaction among subgoals is managed with two AI planning techniqu...

We present a 3-D version of GEM [6], a randomized adaptive layout algorithm for nicely drawing undirected graphs, based on the spring-embedder paradigm [4]. The new version, GEM-3D, contains several improvements besides the adaptation to 3-D geometry. The main result of this work is that for the first time, 3-D layout and presentation techniques are combined available at interactive speed. Even...

This paper introduces a framework of interactive navigating through the web-based UDDI Business Registries. By creating a 2D interactive visual interface, service requesters are able to visually navigate through the large information hierarchies that are usually used to present the UDDI Business Registries. Instead of using the traditional keywords or click-through searching methodologies, whic...

Tightly coupled visualization and analysis is a powerful approach to data exploration especially for clustering. We describe such a specific integration of analysis and visualization for the evaluation of multiple partitions of a data set. Partitions are decompositions of a dataset into a family of disjoint subsets. They may be the results of clustering, of groupings of categorical dimensions, ...

While in clear-cut situations automated analytical solution for data streams are already in place, only few visual approaches have been proposed in the literature for exploratory analysis tasks on dynamic information. However, due to the competitive or security-related advantages that real-time information gives in domains such as finance, business or networking, we are convinced that there is ...

The diagram editor generator framework DIAMETA utilizes meta-modelbased language specifications and supports free-hand as well as structured editing. In this paper we present a layouting approach that is especially well suited for a static layout. It is based on the layout algorithm presented in [MM07a] that uses the two concepts constraint satisfaction and attribute evaluation. This algorithm ...

Financial markets are a fruitful area for data exploration, but the overwhelming size and dimension of the datasets usually prohibit meaningful analysis, especially on a large scale. Thus, there is a need for effective visualization tools to assist in efficiently exploring the data space. In this paper, we present a novel visualization tool that empowers a user with an interactive tool for find...

Visualization is crucial to the effective analysis of biological pathways. A poorly laid out pathway confuses the user, while a well laid out one improves the user s comprehension of the underlying biological phenomenon. We present a new, elegant algorithm for layout of biological signaling pathways. Our algorithm uses a force-directed layout scheme, taking into account directional and rectangu...

In many application domains there is a strong need to produce content both for traditional print media and for interactive media. In order to fully benefit from digital devices, online documents must provide mechanisms to support interactivity and for the personalization of content. Thus, powerful authoring tools as well as flexible layout techniques are needed to display dynamic information ef...
