Week 5: JS + D3

Hello, D3!

Today, we'll be finishing up our crash course in vanilla (non-D3) JavaScript through learning how to manipulate HTML and CSS using only JavaScript. Once we learn to do this the 'normal' way, we'll show how it's more quickly and easily done in D3, and get some practice importing the D3 library and using it to animate elements.

If time, we'll complete our first ever D3 data join, and start to get a handle on D3's famous update pattern!
