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.

We then upgraded our server app to draw a map using D3 and Canvas, which we then outputted to the user as a PNG via a base64-encoded string.

Wasn't that all really pretty weird, but also kind of fun? Writing server-side code is like that. However, it can also be really rather cathartic after spending a bunch of time doing frontend development, which tends to be really finicky due to having to support so many devices. Furthermore, although purely client-side single-page applications were popular for a while, webapps are increasingly pre-rendered via a server, then rehydrated once they arrive for the user.
