I prepared an easier to read version of the diagram (I believe). It's following same basic principles the @D3C4FF's excelent answer does. I was tempted to go with his analogy first, but I thought it wouldn't be appropriate due to recent events and for the current global political climate.
The target (self-portrait of a crested black macaque) is just cute, and the banana just what I thought a convenient analogy for the occasion. Neither are meant to be offensive.
Obviously, a single exploit can deliver multiple payloads to a single or multiple targets. In latter case, a crate of bananas with a single ape, or a crate of bananas in a zoo for multiple targets could be used to describe individual entities involved in the process of exploitation (where the crate would then be an exploit, and bananas in it payloads). ;)
separate entities are colour coded ;)
While this example diagram might seem a bit odd, I actually believe it's suitable beyond just being controversial (as current votes on this post show). Bananas, among other obvious uses, have actually been suggested as a delivery mechanism for medicine before, where normal vaccinations wouldn't be as effective.
The banana peel also denotes an exploit perfectly, since it's later discarded just as the exploit would be, while the payload is consumed and digested by the target through a vulnerability (or in our case, the cute macaque's mouth).
