The red axis is quite confusing, as "total engineers looking for jobs" is a much more useful point of comparison rather than "new engineers" starting from 0 at an arbitrary date.

That is, it's more important to know whether we went from 100K to 110K (and how 110K job-seekers compares to the number of job openings) than from "0" to "10".

Side note: how can the "Q4 so far" graph only go up to ~1-2000? More people than that were laid off from Twitter alone.
