The graph references a paper by Emmanuel Saez that itself references a dataset.
The dataset includes two breakdowns, one including capital gains and one without. The following data is extracted from the capital gains-included set. It also omits the 1913–17 years since those don’t include 90–100 breakdowns.
FIRST_YEAR = 1917
