WWII documentary series with end credits that used a diorama

I remember a series about World War II where the end credits were shown over a camera that flew over a diorama that show the progress of the war that started with normal scenes that slowly transitioned by the end of the credits to bombed out cities. I thought it might be the classic BBC The World at War, but the episodes I've seen on Youtube don't have the diorama.

And the answer is People's Century.
