Abstract. Software development and maintenance is very expensive, and the issues related to the  intellectual understanding associated with the development of new programs are growing at a fast pace. Previous research has shown, that using 3D software visualizations in this field can lead to several advantages. Yhis project’s goal is to analyze current situation in domain of software visualization and visual programming. It deals with various graphics representations of software and corresponding interaction techniques as well. It is finding alternative approaches to software development using visualization and interaction in 3D space.

Abstract. This work concentrates on the problematics of visual programming and visual programming languages as a means for the creation, editing and execution of visual programs. It lists several advantages and disadvantages of this approach. It provides necessary definitions and states the classification of visual programming languages and their paradigms. It also explains several means of formal visual language specification. Existing visual environments and languages are analyzed and their distinguishing traits are explained. It then addresses the representation of programs with the means of graphs and the creation of such graphs. A new notation for representing software based on hypergraphs is presented. A new visual language is specified based on presented notation, together with it’s syntax and execution model. Finally, a visual programming environment for the specified language is presented. It enables the user to create, modify and run programs based on the specified language.

Abstract. The basis of every visualization is data, which can have different forms. Interesting are more complicated structures like common graphs, their generalization in form of hypergraphs and multidimensional data. Hypergraphs have big possibilities, but are not used very often. They could be used for representation of complicated relations, for example ontologies using topic maps. Important aspects of visualization are interaction and clustering of large data. Data visualization can use different metaphors. This approach should make the data more familiar to user by visualization using known images. This diploma thesis brings a new approach to 3D visualization of hypergraphs and multidimensional data using sky metaphor.
