Ok I understand, I guess if the data used to make that map were displayed in a three dimensional image it would appear as a sphere?

 

They say it appears spherical because it's measured uniformaly in every direction from earth. However this does not mean (according to "them") that earth is at the center of the universe. Rather, it would be measured at the same distance from anywhere in the universe and appear just as spherical, because it happened everywhere at the same time. It is a time factor reaching us now and everywhere else in the universe at its current temp 13.7 billion years after the fact.
