I see this is flagged for movement to Commons. I would be happy to see it placed there, but please don't delete here since it is referenced elsewhere including outside of wiki. DeepNorth (talk) 00:26, 18 October 2016 (UTC)
I am the owner of this graphic and I put it up here. It is not clear to me what the system might do to it. I know that the first time it was uploaded, it was deleted because whoever/whatever did the deleting thought I did not have the right to publish it.
If you are here wondering whether or not you can use this graphic, here is your answer:
Yes, with attribution.
If you need some other license it is easy enough to track me down and ask. I am an open source guy so nearly everything I own is up for grabs under very liberal terms.
