This graph represents the initial state of the pandemic. The black dots denote the position of the susceptible population. The red dots denote the position of the infectious population. The virtual environment contains 10,000 population, in which, 70 (0.7%) of them are infectious. This is a challenging scenario because the infectious is heavily spread all over the regions. The density of the environment is set to be 0.02.
