Notional illustrations for histogram plots showing different distributional characteristics of the data. (a) the top panel shows a leptokurtic distribution – here, the daily infection counts for USA across TW1;(b) the middle panel shows a platykurtic distribution – here, the daily infection counts for Brazil across TW1; (c) the lower panel shows a mesokurtic distribution – here, the daily death counts for India across TW1. Note that the distribution is showing a heavy tail for US infection data, no significant tail for India and a light-tail for Brazil
