Visualisation tasks can be categorised into four levels according to the complexity of their search spaces. The workflows for epidemiological modelling, especially during an emergency, can benefit significantly from observational, analytical, and model-developmental visualisation in addition to disseminative visualisation. While visualisation can significantly reduce the time required for information acquisition, it can also enable experts to reason with the data in conjunction with their knowledge about, for instance, related facts and events in the reality, shortcomings in data collection and processing, and scientific understanding about the models concerned.
