This one in particular is very clear:
C++, Ruby and Javascript have the most profanity. They're relatively equal to each other and collectively account for more than 50% of the swearing in commit messages.
C is next, with significantly less swearing.
C# and Java are roughly tied a bit below C.
Python and PHP have, comparatively, almost no swearing.
Was that really so hard? When the data is already subjective (what is and isn't a swear word) and intended almost solely for humor, do we really need more precision than a pie chart offers?
It is at best hyperbolic and at worst dishonest to say you "have no idea" how to interpret this. You have an idea. You just don't have precision.
