Diagramming sentences is a way to SHOW how the words in a sentence are related to each other.
The fun thing about interjections is that they are actually not grammatically related to the rest of the sentence, and sentence diagrams of interjections make that easy to see.
To diagram an interjection, you simply float it on a line hovering above the rest of the sentence.
They are not joined to any other part of the sentence.
That's a pretty good way of showing that they aren't related to any of the other words, isn't it?
