I am trying to compactify Minkowski space, but all I manage
to get is kinds of clovers or squares, while what I'm after
is circles (i.e. the locus of points whose *proper* distance
from the origin is constant).

 Note that I would like to keep it in terms of (y,x) coords,
as that naturally maps to the (t,x) of space-time.
 Can anyone suggest scaling formulas (or fix the diagram)?

Never mind, here it is, at least the upper portion:

The scaling is the obvious one component-wise.  Drawing
full diagrams in Desmos makes things quite more complicated,
indeed I have not actually computed `f_e` as that require
the inverse scaling...
