# Why Use a Graphical Representation? There are three main ways to communicate data: * verbally * numerically * graphically The human brain is extremely good at processing visual information. When it comes to verbal communication, the receiver of the information is forced to process it sequentially. This is very different from information that is conveyed graphically, in that we can process the information in a parallel fashion. Numerically represented information, on the other hand, is difficult to process. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
