TCJA version of "Tax Reform Visualization 1"

@MaxGhenis said in #793:

As an aside: I really like this simple visualization. It'd be cool to have a 2018 version of it for TCJA, and with %chg after-tax income.

I think it would be cool to have TCJA version of "Tax Reform Visualization 1". There shouldn't be huge efforts to (re)produce the new plot.

That sounds like a good idea. How difficult is it to create these plots?

Also would it be the same plot but instead of having these switches you just would have one for TCJA vs current law 2017?
