There are many sequences in the OEIS which have
illustrations like that. These are fully acceptable - you just edit the
sequence and click "I wish to upload a file".

Here are some examples: A256111, A285471.

If the file is over some limit (like 3 megs), then you have
to get one of the administrators to upload it for you
(Charles Greathouse or myself can help with that)
