graphs of irreversible vs reversible?

i kind of understand the definitions of the two and the conditions in which they are true, but why do the curves look so different?

An irreversible expansion happens under a constant pressure, while the pressure for a reversible expansion will vary. So the pressure values will show differently on the graphs.
