Add output (UI/Server)

The next step in building your app is to add an empty plot as a placeholder. Recall that in order to add a plot p assigned to an object named x to a Shiny app, you need to:

Render the plot object using renderPlot({p}).
Assign the rendered plot to output$x.
Display the plot in the UI using plotOutput("x").

The shiny and ggplot2 packages are pre-loaded for you.
