"""This program shows `hyperfine` benchmark results as a box and whisker plot.
|
|
|
|
Quoting from the matplotlib documentation:
|
|
The box extends from the lower to upper quartile values of the data, with
|
|
a line at the median. The whiskers extend from the box to show the range
|
|
of the data. Flier points are those past the end of the whiskers.
