Adobe Illustrator is a powerful drawing software program offered by Adobe. Anyone, regardless of artistic or computer ability, can use Illustrator to draw shapes and lines, create text, or import graphics and pictures. You can use Illustrator to do a layout for a book, create a web page, and the list goes on. The best thing about it is, however, that you can do all these things easily using Illustrator once you learn the program and what different functions and features it provides.
