It shows the movement of Earth’s tectonic plates over the past billion years, and it was posted by one of the co-authors of this study proposing a new, single model of plate tectonic activity that covers the past billion years of Earth’s existence. (Previous models, if I understand the abstract correctly, covered shorter periods—for several-hundred-million-year values of short—and didn’t line up with each other.)
