Join Emma Saunders for an in-depth discussion in this video What you need to know, part of D3.js Essential Training for Data Scientists.
You're not limited to a pre-defined set. If you can conceive of a graphic, you can create it in D3. To make a visualization in D3, you have to code it, format it, and publish it within a webpage. So you need to know the basics of creating and publishing a webpage, in order to use D3. We're going to go over the very basics of HTML and CSS as a refresher, but we do not teach these languages in this course. You will learn D3 quicker if you work alongside me, pausing and testing each step as we go.
DOM is short for Document Object Model, and allows you to see all the elements of your webpage nested within each other. Sometimes you add 47 circles to the webpage, but you can't see them. In these cases, the DOM tree is usually the way to solve the mystery. If you choose to use a different text editor or browser, please ensure you can do these two things. They're crucial to developing in D3.
