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.

What exactly did we do here?

The key is in the three for...each statements that we used. One loops through the array of table header strings, and appends a table cell (td) element with each value into the thead row. There are then two nested .forEach() statements that do the same for each row in the body. We technically only have one row in the body right now, so probably didn't need that messy double for...each, but now all we have to do to add another row to the table is simply append another data array to the rows variable. We'll talk more about Array.prototype.forEach and other array functions in the next chapter.

This might seem like a lot of work for such a simple table, but the advantages of doing it this way are huge. Instead of wasting a bunch of time typing out a totally static table that you'll never use again, you've effectively created a basic JavaScript library that will produce a basic table for you whenever you need it. You could even extend your tableFactory function to do...
