A good rule of thumb when creating an illustration is ______.

A) to make sure your graph communicates only one idea
B) to not label items
C) to use a lot of text
D) to not worry about centering titles and axis labels

It is important for an illustration to communicate its intended message clearly, and focusing on one idea or concept can help achieve this. Labeling items and centering titles and axis labels are also important elements to consider in creating a clear and effective illustration. Using a lot of text, on the other hand, can clutter the illustration and make it more difficult to understand.
