The countries are ordered on the bend line according to their rank, so the 1-dimensional spatial coordinate system describing this line does have meaning.
This somwhat unusual representation has the advantage that they managed to represent all datapoints with a well readable font on a graphic that fits well even on a phone’s screen, and it’s sort of eye-catching.
It’s pretty unintuitive, though. I had to actually read and analyse it rather than just view it.

Why not just use a coloured map instead? Presumably that would fit in roughly the same aspect ratio.
