Interaction with graphics, either through Shiny's built-in listeners or through JavaScript integration, is the last topic related to specifically developing applications in Shiny. It is supposed that, after these nine chapters, the reader has acquired the main concepts required to code their own applications. Of course, the world of R and web programming (HTML, JavaScript, and so on) is infinite and impossible to cover thoroughly in a book.
