Book Description
Pictorial representations are very useful for humans to understand complicated relations or structures. This is the reason that the user interface of information systems is strongly required to visualize many kinds of information in a wide variety of graphical forms. At present, however, only some very specialized visualization techniques have been developed probably because the generality in the visualization has not been appreciated correctly. This book presents a visualization framework for translating abstract objects and relations, typically represented in textual forms, into pictorial representations, and describes a general visualization interface based on this framework. In the framework, abstract objects and relations are mapped to graphical objects and relations by user-defined mapping rules. The declarative nature of the mapping rules provides users with more global and more flexible layout capabilities. Also presented is an algorithm for drawing general undirected graphs which can be used to visualize network structures as network diagrams. The proposed visualization framework is shown to be general enough to be applied to various types of visualization problems, such as the visualization of semantics of natural language sentences, the generation of diagrams for data structures and program structures, and the drawing of database schema. Examples of all these problems are shown with actual mapping rules and pictorial results.

Book Description
An accessible primer on how to create effective graphics from data This book provides students and researchers a hands-on introduction to the principles and practice of data visualization. It explains what makes some graphs succeed while others fail, how to make high-quality figures from data using powerful and reproducible methods, and how to think about data visualization in an honest and effective way. Data Visualization builds the reader’s expertise in ggplot2, a versatile visualization library for the R programming language. Through a series of worked examples, this accessible primer then demonstrates how to create plots piece by piece, beginning with summaries of single variables and moving on to more complex graphics. Topics include plotting continuous and categorical variables; layering information on graphics; producing effective “small multiple” plots; grouping, summarizing, and transforming data for plotting; creating maps; working with the output of statistical models; and refining plots to make them more comprehensible. Effective graphics are essential to communicating ideas and a great way to better understand data. This book provides the practical skills students and practitioners need to visualize quantitative data and get the most out of their research findings. Provides hands-on instruction using R and ggplot2 Shows how the “tidyverse” of data analysis tools makes working with R easier and more consistent Includes a library of data sets, code, and functions

Book Description
This book is about using interactive and dynamic plots on a computer screen as part of data exploration and modeling, both alone and as a partner with static graphics and non-graphical computational methods. The area of int- active and dynamic data visualization emerged within statistics as part of research on exploratory data analysis in the late 1960s, and it remains an active subject of research today, as its use in practice continues to grow. It now makes substantial contributions within computer science as well, as part of the growing ?elds of information visualization and data mining, especially visual data mining. The material in this book includes: • An introduction to data visualization, explaining how it di?ers from other types of visualization. • Adescriptionofourtoolboxofinteractiveanddynamicgraphicalmethods. • An approach for exploring missing values in data. • An explanation of the use of these tools in cluster analysis and supervised classi?cation. • An overview of additional material available on the web. • A description of the data used in the analyses and exercises. The book’s examples use the software R and GGobi. R (Ihaka & Gent- man 1996, RDevelopment CoreTeam2006) isafreesoftware environment for statistical computing and graphics; it is most often used from the command line, provides a wide variety of statistical methods, and includes high–quality staticgraphics.RaroseintheStatisticsDepartmentoftheUniversityofAu- land and is now developed and maintained by a global collaborative e?ort.

Book Description
This volume presents a selection of the contributions to the Seventh Workshop on Informatics and Psychology. The theme of the workshop was Visualization in Human-Computer Interaction. Visualization is nowadays recognized as an important aspect of user-oriented human-computer interfaces. Both informatics and psychology are concerned with this topic. In informatics, the technology is being developed which makes visualization and interaction based on visual concepts feasible. Another important trend in informatics is the development of prototypical solutions. Visual programming, visual languages, graphical interfaces, visual representations and many other keywords characterize current efforts in this field. Psychologists are working on the question of how people represent knowledge visually and how they can take advantage of visual representations when solving tasks.

Book Description
Recipient of the Mathematical Association of America's Beckenbach Book Prize in 2012! Group theory is the branch of mathematics that studies symmetry, found in crystals, art, architecture, music and many other contexts, but its beauty is lost on students when it is taught in a technical style that is difficult to understand. Visual Group Theory assumes only a high school mathematics background and covers a typical undergraduate course in group theory from a thoroughly visual perspective. The more than 300 illustrations in Visual Group Theory bring groups, subgroups, homomorphisms, products, and quotients into clear view. Every topic and theorem is accompanied with a visual demonstration of its meaning and import, from the basics of groups and subgroups through advanced structural concepts such as semidirect products and Sylow theory.
