There also seems to be a mistake in the first map. Down where it says "The least obsessed with spending time online", all three countries actually have the same time as the country above them, from the most obsessed. Japan should have 3:45, but it's noted as 9:38, same as South Africa above it. I could at least tell their actual average from looking at the country, but I can't do the same with Denmark since the text is too small on the map for it.

At least the second and third map don't have that issue, but yes, the color scheme is odd.
