I don't expect much of anything from either call.

You're setting up a Mercator projection, which projects the north pole
to +infinity and the south pole to -infinity. Then you tell it to
produce a plot of finite size using that projection, where the north
pole is at the top of the plot and the south pole is at the bottom of
the plot. I don't expect it to work, and I wouldn't be surprised by any
particular failure mode.
