Use the Pharo interactive development environment to significantly reduce the cost of creating interactive visualizations. This book shows how Pharo leverages visualization development against traditional frameworks and toolkits.Agile Visualization with Pharo focuses on the Roassal visualization engine and first presents the basic and necessary tools to visualize data, including an introduction to the Pharo programming language. Once you’ve grasped the basics, you’ll learn all about the development environment offered by Roassal. The book provides numerous ready-to-use examples. You’ll work on several applications, including visualizing the training phase of reinforcement learning (a powerful machine learning algorithm) and generating software visualizations from GitHub. This book covers aspects that are relevant for engineers and academics to successfully design and implement interactive visualizations. What You Will LearnImplement agile data visualization using the Pharo programming languageChart, plot, and curve using GrapherBuild and draw graphs using MondrianImplement reinforcement learning (Q-Learning, from scratch) and use visualizations to monitor learning and state explorationUse GitHub Action to generate software visualizations (UML class diagram, test coverage) at each commit Who This Book Is For Programmers with some prior exposure to data visualization and computer vision who may be new to the Pharo programming language. This book is also for those with some Pharo experience looking to apply it to data visualization.

Cover classical algorithms commonly used as artificial intelligence techniques and program agile artificial intelligence applications using Pharo. This book takes a practical approach by presenting the implementation details to illustrate the numerous concepts it explains. Along the way, you’ll learn neural net fundamentals to set you up for practical examples such as the traveling salesman problem and cover genetic algorithms including a fun zoomorphic creature example. Furthermore, Practical Agile AI with Pharo finishes with a data classification application and two game applications including a Pong-like game and a Flappy Bird-like game. This book is informative and fun, giving you source code to play along with. You’ll be able to take this source code and apply it to your own projects. What You Will LearnUse neurons, neural networks, learning theory, and moreWork with genetic algorithms Incorporate neural network principles when working towards neuroevolution Include neural network fundamentals when building three Pharo-based applicationsWho This Book Is ForCoders and data scientists who are experienced programmers and have at least some prior experience with AI or deep learning. They may be new to Pharo programming, but some prior experience with it would be helpful.

Crafting a visualization requires short and incremental developments, often costly both in time and effort. Agile Visualization promotes the use of the Pharo interactive development environment to significantly reduce the creation of a visualization. Pharo significantly leverages a visualization development against traditional visualization frameworks and toolkits. This book focuses on the Roassal visualization engine. Agile Visualization first presents the basic and necessary tools to visualize data. The development environment is subsequently described. The book then covers a domain-specific language framework to design and implement expressive and composable visualizations. Several applications are presented, covering epidemiological models, geographical information, network latency, and source code software analysis. Agile Visualization covers aspects that are relevant for practitioners, businesses, and academics to successfully design and implement a visualization.

Pharo is a dynamic object-oriented programming language. Pharo's model and syntax are uniform, simple and expressive. These properties, when added to a powerful and flexible programming environment, regularly attract new developers. Pharo leverages the software building experience to its best. It offers open and object-oriented programming environments and libraries. The book covers a large spectrum of topics ranging from central language aspects to innovative frameworks and libraries. This book contains unique material often presented in a tutorial form with many experiences to carry on. Everybody will learn something reading this book: programmers familiar with Pharo will enjoy the highlights made of some particularly beautiful aspects of Pharo as well as discovering new and powerful frameworks. Deep into Pharo presents internal aspects of Pharo that proved to be important for academic, business and development perspectives.
