People say Russia, Canada and Greenland look big in the Mercator projection, but what they miss is it makes Antarctica enormous, your app shows it nicely. So much so that many maps just cut off the bottom otherwise it looks a bit silly, but then the equator isn't in the middle.

The mercator projection has neither a top nor a bottom, it extends infinitely upwards and downwards. Hence all visualizations of it cut it off at some arbitrary point. Making antarctica humorously large does nothing besides make a point.
