I watched a video by 3Blue1Brown - "Simulating an Epidemic", which featured an interesting simulation UI. I wanted to replicate it with then new-ly learnt web technologies, mainly JavaScript and React.js.

The core idea was to simulate the movement of people with varying factors such as density (the number of people within a specific area), movement speed, infection radius (how close people come into contact with each other) and infection chance (strength of a person's immune system).

By playing around with these features, we can grasp how human behaviour affects the spread of epidemics. This serves as a reminder for people to take preventive measures to protect each other during an epidemic.
