Graph layout algorithms are used to compute aesthetic and useful visualizations of graphs. In general, for graphs with up to a few hundred nodes, force-directed layout algorithms produce good layouts. Unfortunately, for larger graphs, they often get stuck at local minima and have high computational complexity. In this paper, we introduce a novel message passing technique for graph layout. The k...

In this paper we present a set of extension techniques to stabilize interactive dynamic graph layout algorithms. It works with different existing Focus & Context methods. We first deal with the initial placement of newly inserted nodes to mitigate acting forces in the layout algorithm. Then, their influence on the existing layout is gradually increased to create a smooth transition between the ...

Many classical graph visualization algorithms have already been developed over the past decades. However, these algorithms face difficulties in practice, such as the overlapping node problem, large graph layout and dynamic graph layout. In order to solve these problems, this paper aims to systematically address algorithmic issues related to a novel framework that describes the process of graph ...

We introduce a new free, open-source compound graph editing and layout framework named Chisio, based on the Eclipse Graph Editing Framework (GEF) and written in Java. Chisio can be used as a finished graph editor with its easy-to-use graphical interface. The framework has an architecture suitable for easy customization of the tool for end-user’s specific needs as well. Chisio comes with a varie...

The inter-cell layout problem is discussed and a mathematical formulation for material flow between the cells is presented. The problem is modeled as a quadratic assignment problem (QAP). An ant algorithm is developed to solve the formulated problem. The performance of the proposed ant algorithm is compared to the facility layout algorithms such as H63, HC63-66, CRAFT and Bubble Search as well ...

We developed a visual system generator called “Rainbow” which can handle layout constraints. The system can interactively layout figures while parsing them and make the parsed figures more understandable. Rainbow can deal with “soft layout constraints.” Soft layout constraints automatically layout entire figures by using graph drawing algorithms. Soft layout constraints are more flexible than c...

Motivations for drawing hierarchical structures are probably as diverse as datasets to visualize. This ubiquity of tree structures has lead to a manifold of tree layout algorithms and tree visualization systems. While many tree layouts exist, increasingly massive data sets, expanding computational power, and still relatively limited display space make tree layout algorithms a topic of ongoing i...

We address the new problem of puzzle layout as a new application of graph drawing. We present two abstract models of puzzles, permutation puzzles and cyclic puzzles, which can be modeled as puzzle graphs. Based on these models, we implement two puzzle generators and produce various layouts of the puzzles using graph drawing algorithms. Using these puzzle generators we can create new puzzles. Fu...
