Does matplotlib have a convenient way to produce a histogram of
categorical (possibly non-numeric) values? I can do it with bar(),
but there's a fair amount of boilerplate involved (calculating the
frequencies, counting the number of distinct values, etc.). This
seems like it would be a common task, so I'm wondering if there's a
function for it, or, failing that, a standard recipe.

no path, and leave a trail."
