 ### Text (`annotations`)
 
-
 Text can be placed at a point, as a marker is. To place text, the desired text and a position need to be specified along with any adjustments to the default attributes.

-The graphic shows that `fontsize` adjusts the displayed size and `rotation` adjusts the orientation. (The graphic also shows a need to manually override the limits of the `y` axis, as the `Point 5` is chopped off; the `ylims!` function to do so will be shown later.)
+The graphic shows that `fontsize` adjusts the displayed size.
 
 
 Attributes for `text`, among many others, include:
 
 
   * `align` Specify the text alignment through `(:pos, :pos)`, where `:pos` can be `:left`, `:center`, or `:right`.
-  * `rotation` to indicate how the text is to be rotated
   * `fontsize` the font point size for the text
   * `font` to indicate the desired font
 
 
+Annotations with an arrow can be useful to highlight a feature of a graph. This example is modified from the documentation and utilizes some interval functions to draw an arrow with an arc:

+```{julia}
+g(x) = cos(6x) * exp(x)
+xs = 0:0.01:4
+
+_, ax, _ = lines(xs, g.(xs); axis = (; xgridvisible = false, ygridvisible = false))
