Coolio! :) I built something similar [0] a while ago. My goal was to _visually_ demonstrate how fast a virus can spread. I wanted to make it is easy for everyone to get an understanding about exponential growth and how different measures can have a great impact on the spread of a virus.

Disclaimer: This is an unpolished toy project. It was built in a weekend by simple dude who likes to code but has no idea about virology and epidemiology.
