South America is the most sparsely populated continent except Australia and Antarctica. The Amazon and Patagonia regions host very little human population (thank goodness).
So South America would always show up as a few big coastal cities with vast emptiness inside, even with huge search penetration on Google's cool visualization. It really doesn't tell you much either way without raw data.
