Create a BoxPlot. whiskerPercentile controls the percentile at which
data points are considered outliers and plotted as individual points.
For any x, a percentile of x is equivalent to a percentile of 1 - x.
For example, if whiskerPercentile is either 0 or 1, no data is plotted as
individual points and the whiskers extend all the way to the extrema.
