I followed @realjasonisaacs for his data gathering and analysis of COVID-19 in Ventura County. I wrote a simple Python3 script (using graphics.py) that provides a visualization of the pandemic. The simulation has a few parameters, but it is essentially a simulation of people’s random but relatively confined movements. It starts with one sick individual in the center, and a population of 300 healthy individuals. What was surprising was how easily I was able to simulate the situations presented by Jason Isaacs (e.g., exponential versus logistic growth) with my simple code. See a recording of a run of a typical development of the pandemic.
