Overview of this book

Want to get started with impressive interactive visualizations and implement them in your daily tasks? This book offers the perfect solution-D3.js. It has emerged as the most popular tool for data visualization. This book will teach you how to implement the features of the latest version of D3 while writing JavaScript using the newest tools and technique You will start by setting up the D3 environment and making your first basic bar chart. You will then build stunning SVG and Canvas-based data visualizations while writing testable, extensible code,as accurate and informative as it is visually stimulating. Step-by-step examples walk you through creating, integrating, and debugging different types of visualization and will have you building basic visualizations (such as bar, line, and scatter graphs) in no time. By the end of this book, you will have mastered the techniques necessary to successfully visualize data and will be ready to use D3 to transform any data into an engaging and sophisticated visualization.

Flow control

JavaScript is a single-threaded asynchronous language, meaning that it doesn't really fork in the same way you would expect a multi-threaded language like C++ to, and thus a function blocking the main thread causes everything to grind to a halt. Luckily, the asynchronous part of that means functions generally won't do this, and functions can be written so that the next one can fire before the first one finishes.

On the one hand, this is one of the most interesting and powerful aspects of JavaScript as a language. On the other, it makes things somewhat more difficult to reason about, and adds a degree of complexity to organizing one's code. While you can do pretty much anything without getting too bogged down in the JavaScript event model, the one place where the asynchronous nature of JavaScript is particularly visible is when you make a request -- no matter how fast broadband Internet gets, so long as it conforms to the standard model of physics, there will always be some degree...
