Part 1 D3.js fundamentals

Welcome to the world of D3.js! We know you are impatient to build mind-blowing data visualizations. You're going to get there soon, we promise! But first, let's make sure that you get the basics right. The notions you will encounter in this section are the ones you will meet repeatedly in your D3 journey, and understanding them in depth will give you a definite advantage once you approach more complex visualizations.

In chapter 1, we will discuss why and when someone might want to use D3 and its ecosystem. We'll also introduce concepts that will support your learning: drawing SVG shapes, manipulating data with JavaScript, and method chaining.

Then, in chapters 2 and 3, we'll use D3 to build a bar chart. For that, we'll discuss how to manipulate the DOM and work with data. In chapters 4 and 5, we'll already build more complex visualizations with the help of D3's shape and layout generators. We'll finish this section with distributions, a subject that all data visualization practitioners meet from time to time.
