The first map of galaxy distribution, looking like a thin slice of pie, shows only a small sector of the sky, not enough yet to capture the full dramatic effect of some earlier cosmic maps that have revealed, for example, the existence of a "great wall" of linked galactic clusters stretching across some one billion light-years of space.
