Normally, graphics are the central elements of data visualization as they are an intuitive and clear technique to display results, especially on a computer. In this chapter, you will learn about the different graphical procedures in R and how to integrate them in your Shiny applications.

By now, you must have acquired a clear notion of how to structure a Shiny web application and the different types of outputs that can be used. The purpose of this chapter is to complement this with a series of techniques to display data in a graphical way. In this way, unlike other software including commercial ones, R provides you with the possibility of displaying graphics (and any information in general) practically without restriction.

The importance of this goes far beyond a technical question. In alignment with GNU philosophy, no technical restriction implies no restriction in communication, which finally means "free" as in "free speech".
