This would better be described as a way to create a histogram using
any arbitrary bins of your own devising; pretty cool indeed, since you
can design those bins in whatever way is useful. It does require you
to sort your array beforehand, and so in this case would be less
efficient than just taking the histogram of the log of your data.
