Nit: It can be misleading to show cumulative metrics. You have to mentally take the first derivative. And cumulative metrics never go down! (Guilty of this myself.)
I'd prefer if the chart at the top were daily/monthly queries. Then you'd quickly see their huge growth, but relative stagnation in 2021.
I was mislead by the chart too, i had assumed it was a chart of daily queries (getting a daily average to smoothen it out makes sense to an extent, but a 365 day average when you have this many data points?), however one redeeming quality is they let you change the day average from 365 to say 5 days. Despite that, they still grew by 25% in 2021 (which is much less than their growth in 2020 of ~60%, but still not at the level of stagnation)
