but it does have consistent dots for the X axis, every year.

I'm not sure what you mean by "consistent"...

It's one a year up to dec 2025, then after that do you notice how the lines goes up and down super fast?

That's because there's a shit ton more dots there, even if they're not large enough to see, any change in slope means there's a new data point.

Doing one a year and then one a week is not consistent.

but part of the point of the graph is showing how billionaires have almost tripled their wealth since 2022, at the expense of everyone else.

Right...

The person who made it likely just crammed two different graphs (or underlaying datasets) together, and most likely had a chatbot do it for them.

That's actually why I blocked the "data is beautiful" community here, it was just people who know nothing of statistics jamming two graphs together like that accomplishes anything except making the information harder to read, which making the information easier to read is the literal purpose of graphs.

Most people never take even a single stats class, and just don't know what the fuck they're doing.

Edit:

I'm also confused, why did you downvote me and ask me to explain?

It makes it look like you just want to argue instead of learn. I'm happy to help, but I really don't care what you learn, if you just want to argue find someone else.
