The percentage growth of confirmed COVID-19 cases: the reasons for a graph
Focusing on Italy, here I explain the reasons why I use a graph that represents the evolution in the daily percentage growth of total confirmed #COVID19 cases. In particular, (i) I compare this type of graph with one that represents the absolute increases of COVID cases, (ii) discuss how this graph allows to compare countries and (iii) point out how one can easily calculate the doubling time of cases.
