Tree Chart with Hierarchical Data in D3.

When I was learning D3, although there are  a lot of great resources to learn from, I can rarely find detailed code explanations for me to fully understand how everything works, making it difficult to recreate a chart on my own without additional searches.

So I want to fill this whitespace with a series of D3 (v4) line-by-line code explanations for each chart I create, sharing with you what I’ve figured out. Comment if you want me to create a video series!

Let’s kick off this series by building a tree chart like the one below.
