Software Visualization: From Theory to Practice was initially selected as a special volume for "The Annals of Software Engineering (ANSE) Journal", which has been discontinued. This special edited volume, is the first to discuss software visualization in the perspective of software engineering. It is a collection of 14 chapters on software visualization, covering the topics from theory to practical systems. The chapters are divided into four Parts: Visual Formalisms, Human Factors, Architectural Visualization, and Visualization in Practice. They cover a comprehensive range of software visualization topics, including\n\nVisual programming theory and techniques for rapid software prototyping and graph visualization, including distributed programming.\n\nVisual formalisms such as Flowchart, Event Graph, and Process Communication Graph.\n\nGraph-oriented distributed programming.\n\nProgram visualization for software understanding, testing/debugging and maintenance.\n\nObject-oriented re-design based on legacy procedural software.\n\nCognitive models for designing software exploration tools.\n\nHuman comprehensibility of visual modeling diagrams in UML.\n\nUML extended with pattern compositions for software reuse.\n\nVisualization of software architecture and Web architecture for better understanding.\n\nVisual programming and program visualization for music synthesizers.\n\nDrawing diagrams nicely using clustering techniques for software engineering.
