In section 2.2.1 Selections and binding (MEAP V03), under heading .ENTER() AND .EXIT(), the book states:

.enter() fires four times,


Shouldn't that be eight times, as the array contains eight values?

Similarly under the .ATTR() heading (and possibly other mentions of the word "four").

Yes, of course you're right. I think my original data (even before 1st edition) had 4 cities and we just never noticed this error.
