> the area under the excess deaths is misleadingly large

Yes, it's always a trade-off of course, but I generally prefer to sqrt() the radial axis of this kind of plot so it is equal-area.

Author here. That is a good idea. I will try that.

I have regenerated the graphs to use the square root of the count as the radius to keep the area constant, as others have suggested. I appreciate the feedback.

Hey, nice one — I’m glad I could give a useful suggestion…

Unfortunately it doesn’t make the numbers less tragic.

Curious how this works, trying to do the maths in my head, but polar integration not my strong subject.

Area of a slice is angle/2 x r^2.

Whole circle (angle = 2 x pi) is pi x r^2
