In this chapter, we will focus more on understanding what we want to say with the data that we are presenting, and how to say it effectively. We will present some new techniques and plots, but all will be underlined by understanding of the information we want to convey to the user. Let's ask the questions. Why do we want to present information in this state? This is the most important question that should be asked during the data exploration phase. If we miss the opportunity to understand the data and present it in a certain way, the viewer, then, is not going to understand the data correctly, for sure.
