onstants used to add some
padding around the data to ensure that they are placed some distance
away from the axes. Use the convenience function <code><a href="https://ggplot2.tidyverse.org/reference/expansion.html" class="external-link">expansion()</a></code>
to generate the values for the <code>expand</code> argument. The defaults are to
expand the scale by 5% on each side for continuous variables, and by
0.6 units on each side for discrete variables.</p></dd>
