The chart should be somewhat descriptive in the correlation, and usually processing in intensity. The single death count having two different levels of funny isn’t really explained by the chart, which isn’t a real statistical analysis which might have odd data points like that, but instead is an extra joke.
As a joke, it doesn’t portray itself well if the axies aren’t swapped. When swapped, the joke is pretty obvious and understandable.
I think they technically do, with stuff like Helldivers 2, Spiderman games, etc. I have Helldivers 2, but stopped playing it for a while in protest when they tried to make you use a PlayStation account for it, essentially cutting off a bunch of players in countries PlayStation doesn’t operate in.
