1 Introduction
Visual analytics (VA) tools are increasingly used in the field of epidemiology and public health [6 , 20] , particularly, for the surveillance and management of infectious diseases with the potential of emerging pandemics. Scientists need to analyse a large amount of data at different scales for predictions with mathematical models. This is where VA tools help in gaining insights from the large and complex data sets. Based on these insights, scientists can advise decision makers involved in the control of infection events to make informed decisions.
