I think what you are asking for is graphs illustrating Zipf’s law. Google that. The links at the bottom of the Wikipedia page give graphs from various languages using online corpora.
Regrettably the Zipf’s Law topic here doesn’t have any content yet.
Not sure the graphs would look essentially different, whatever the register of language is: the tail drops off pretty steeply anyway, which is the point of it being a logarithmic distribution.
