🦠 Epidemic Wavefront Speed (2D)

2D Canvas simulation of Fisher-KPP reaction-diffusion epidemic spread. Click to seed an outbreak, tune infection rate r and diffusion coefficient D, and watch the theoretical wave speed c=2 root(rD) match the measured front propagation speed.

⚙ Under the hood

A 2D Fisher-KPP reaction-diffusion companion to the 3D epidemic wavefront model, focused purely on wave speed: click to seed an outbreak and watch a real travelling infection front spread outward across a grid. Tune the infection (growth) rate r and diffusion coefficient D and compare the theoretical wave speed c=2sqrt(rD) to the measured front speed live.
