Good morning,
Well, I think that graphs and plots are not topics I've been introduced to, so no. But about the other two, I hope I got the definitions right a dimension=1st dimension is a point/dot, 2nd dimension is 2 dots connected with a line and 3rd is a line that has a third line added that goes out of the 2D, adding depth. So I would call it like a form that the particular space takes. So space should be by that thinking a place, where all the matter and antimatter can "exist" and where basically everything happens therefore even the surface of Earth is also space. Of course correct me if I'm wrong. I know just the dumbed down definitions, really. Always glad to learn more since Wikipedie and other sources never really answer anything because of how broad they are.
