SIR model on a Watts-Strogatz small-world network (N=100). Each node is Susceptible (blue), Infected (red), or Recovered/immune (gray). Infected nodes spread disease to neighbors at rate β; they recover at rate γ. Rewiring probability p interpolates between regular ring lattice and random graph — small-world topology dramatically accelerates epidemic spread.
