For the highest level graphics (elegant, custom, expensive), enter the crunched
data or the graphical output into Adobe Illustrator. ... This program gives
complete control over typography, line weight, color, grids, layout—just
what we need for doing graphical work. It is a serious, complex design program;
you may want to work with real graphical designers who will surely know their
way around Illustrator.
