There have been discussions about how to incorporate graphics, which
have failed to come to any consensus. Nobody is particularly willing
to put a badly-formatted batch of raw numbers into git though, because
it'd be impossible to do any incremental updates on it and still have
useful git history. There are also a bunch of questions about whether
the graphics would work in all the output formats we try to support.
This particular example doesn't really seem compelling enough to
justify finding a way over those hurdles ...
