🦠 Disease Spread — Spatial SEIR Model (2D)

A 2D Canvas SEIR epidemic model: watch a disease spread cell-by-cell across a grid of Susceptible, Exposed, Infectious, Recovered and Vaccinated cells. Adjust transmission, incubation and recovery rates and see R0 and the epidemic curve update live.

⚙ Under the hood

A 2D Canvas cellular-automaton SEIR model: each cell on a grid is Susceptible, Exposed, Infectious, Recovered or Vaccinated, and infection spreads locally from its eight neighbours each step. Adjust the transmission, incubation and recovery rates, seed vaccination, and click or Shift-click the field to start outbreaks or firebreaks while watching the live SEIR curve and R0 estimate.
