I don't think I've ever seen what appears to be a line graph loop back on itself.

Visualise it as a 3d graph seen from the top.

Math people are cringing.

But in this graph it's correct, isn't it?

A bit of a strange choice of axis, but technically it's correct, I think.
We see how during COVID people died earlier although expenses went up (didn't check the dates, but I guess that's the thing?), and afterwards expenses went down, but people grow older again
Or do I completely misunderstand this?

Yeah, it's correct. What they did is, for every year they place a dot with respect to x and y axis, then connected the dots. An unusual graph, but works well for this situation, IMO.

I don't think they're cringing, this is perfectly correct.

By the definition:

A function f from a set X to a set Y is an assignment of one element of Y to each element of X.

This is not a function graph, though. It is a Connected Scatterplot.

I have a degree in math and I'm not cringing
