In 2020, the worldwide pandemic of COVID-19 had a profound impact on society. One of the most important metrics that is being used to investigate the effectiveness of various interventions to control the spread of the pandemic is R, the effective reproduction number. It is talked about extensively in the news, and a wide-ranging array of different interventions are put in place by governments with the aim of getting R below 1 to curb the spread of the disease. In this abstract, we will investigate what R means from a graph drawer’s perspective and aim to open up interesting and relevant research avenues.
