title: Seaborn.countplot : order categories by count
body: <p>I know that <a href="https://seaborn.pydata.org/generated/seaborn.countplot.html" rel="noreferrer"><code>seaborn.countplot</code></a> has the attribute <code>order</code> which can be set to determine the order of the categories. But what I would like to do is have the categories be in order of descending count. I know that I can accomplish this by computing the count manually (using a <code>groupby</code> operation on the original dataframe, etc.) but I am wondering if this functionality exists with <code>seaborn.countplot</code>. Surprisingly, I cannot find an answer to this question anywhere.</p>
