What is 'Graphic design'?

Two last semesters, I've learned how to design some nice things but I've considered seriously "What is Graphic design?".
According to Hollis, P. : “Graphic design is the business of making or choosing marks and arranging them on a surface to convey an idea."
The difinition of 'Graphic design' gives mehe first thinking about graphic design. Belong to this difinition, I tried to translate it to 'another language' (it's not normal language). I used some pictures, icons and symbols to translate the difinition of "Graphic design".

I know that I can't translate meaning as same as the author's definition. So, how many percentages are the same as the original definition?
