There are slight changes, although I'm cannot tell if these are sufficient to skirt the Creative Commons license applied to Wikipedia images. Someone more knowledgeable than I will have to address that. If not, perhaps someone more skilled than I with legal language could Contact the MSGC and advise that they give appropriate citation.

I'm interested to know the partial pressure of CO2 down at liquid nitrogen temperate -- can I assume the slope of the graph in this article just carries on down at the same rate?

There shouldn't be a boundary between supercritical fluid and liquid/gas. That is the defining principle- no abrupt phase transformation occurs on traversing past the dotted lines on this diagram. It would be more useful to indicate a supercritical 'region' beyond the critical temperature
