A graph is the black rectangle that you get, when you choose
"Put->Graph" and it's the black rectangle surrounding arrays. Now,
what use is it? You can put an array, a list of numbers, into a graph. 

Did you notice, that everytime you do "Put -> Graph" you get asked, if
you want to put it "in new graph" or "in last graph"? Normally you
have every array in its own graph, but you can also put many arrays
into a single graph, for example, to see how many sinesums add up to a
rectangle curve etc.

Personally I don't use this functionality at all in real life. I don't
even use arrays in real life a lot, I only use [table].

Ciao
