In graphic design, it is possible to make illustrations. In this case, I show you the three illustrations you can do in Illustrator.

First we have the Bidimensional illustration; An illustration that is based on shapes such as circles, and squares. In this case, I have made a Bidimensional illustration of headphones.

Here we have the monolinear illustration. An illustration that is made only with strokes and lines; As in this case, a monolinear illustration of carrots.

And finally, we have the Rubberhose illustration. An illustration style based on caricatures from the 30s. In this case, an illustration of a mouse with shoes, illustrated in the Rubberhose style.
