Ask HN: Covid Network Simulation?

Sorry to ask, but I cannot find a COVID simulation that was on HN after searching:

Tried...

- "simulation COVID" - "simulation network" ...etc.

It was a cross between [this site](https://www.adiiyengar.com/blog/20200412/covid-19-infection-model) in regards to animation and the thorough posts of ciechanow.ski 's great contributions.

If anyone has an ideas, I'd be stoked.
