If you’re like me, then you may agree that visual communication is more effective than verbal or written. All of course are valuable, but visual has certain advantages. The first known type of this communication comes from our distant ancestors who painted on cave walls thousands of years ago. They left behind scant
evidence to inform us of their lifestyle, however through the efforts of archaeology, these crude drawings help us to understand what they had experienced, what they were witness to, and what they were trying to say.
