The paper introduces a concept of attributed context-sensitive graph grammars. The graph grammars are a graphical generalization of the textual grammars and can thus be used to specify the syntax of graphical programming or modeling languages. The attributed graph grammars extend the basic graph grammars with definitions of attributes and the associated attribute evaluation rules. By analogy to...

The visualization rules of TRIP systems are a set of mapping rules that maps source data into the high-level representation of target picture. The data of this representation consists of geometric graphical objects and geometric constraints among them. When the visualization rules have some bugs, the TRIP system cannot solve the constraints properly and cannot generate a target picture. In orde...

Diagrams are always used when communicating complex situations. As a special case, dynamic processes like the token game in Petri-nets are made clear using dynamic diagrams. Animation techniques have to be used in order to achieve a comprehensible visualization. The paper discusses dynamic diagram languages with animations, i.e., animated diagram languages, and how to specify them. Specificatio...

We describe an R package named huge which provides easy-to-use functions for estimating high dimensional undirected graphs from data. This package implements recent results in the literature, including Friedman et al. (2007), Liu et al. (2009, 2012) and Liu et al. (2010). Compared with the existing graph estimation package glasso, the huge package provides extra features: (1) instead of using F...

The large number of bases in a DNA sequence and the cryptic nature of the 4-alphabet representation make graphical visualization of DNA sequences useful for biologists. However, existing 3D graphical representations are complicated, whereas existing 2D graphical representations suffer from high degeneracy, and many features in a DNA sequence cannot be visualized clearly. This Letter introduces ...

In this paper we present a prototypical implementation of a graphical tool for creating and editing (DL-safe) SWRL rules. The tool uses a graphbased approach to model rules expressed in the SWRL language. Rules are built from concepts and roles defined in an OWL ontology. Such a knowledge base can be visualised and edited in a user-friendly interface. Moreover, the presented tool provides metho...

Graphical rewrite rules are often used in programming environments for children. These rules consist of two parts: a left-hand side, which is visually matched in the environment, and a right hand side, which replaces the matched area. Programs using graphical rewrite rules typically describe behaviour 2D visual simulations where the program describes how visual agents move around a 2D space and...
