This chapter is intended to be a mere introduction to the graphical capabilities of R and how they can be inserted into Shiny web applications. As it was already mentioned, good visualizations are the key to success with this kind of tool, and for this reason, it is always useful to master as many resources as possible. However, building good applications does not rely only on a technical fact (that is, being able to code it) but also on other soft skills that are related more to business understanding, generating impact, and so on. The last chapter of this book covers the development of an application with Shiny from scratch in a hypothetical real-world situation where some problems related to this communicational aspect of the application are presented and solved.

Next chapter goes back to Shiny package specifics again and will cover some advanced functions that will definitely broaden the horizons of your application's possibilities with just a few lines.
