How is this graph even possible? For more than one year the global death toll for Sars-Cov-2 has oscillated between ~5,000 deaths a day to ~20,000 deaths a day creating a pattern that is almost ECG like in its uniformity.  Answers on a postcard please, because we do not see anything natural about this graph.
