I have:
Would use as an icon button to display a dialog explaining coordinate systems when uploading data.
Proposing the current axis-arrow icon, with the i found in car-info in the top right corner?

@mattcorner ^ Is that what you meant?
Yep, looks good to me
Would you be able to share the svg path so that I can use in a project until its officially released?
@mattcorner Added it, should be on the website once the cache clear ~5 mins.
@goyney I was 50/50 on this one also. But axis information icon makes sense to have and I couldn't think of another way to design it. We can always revise this later.
