ABSTRACT
On the other hand, active diagrams include implied or real
motion or movement, in addition to passive labeling to illustrate the
action of a process or event. Thus, an effective active diagram
should, at once, dissect an object or event, labeling its parts, and
attempt to illustrate actual or implied movement. So, while a pas-
sive diagram of the human heart would likely just label and perhaps
explain the chambers and arteries of the heart, an active diagram of
the heart might attempt to actually illustrate how blood flows
through the heart.
