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)
