🦠 Bacterial Colony Growth (2D)

A 2D top-down petri-dish simulation of bacterial colony growth: logistic population growth dN/dt=rN(1-N/K) combined with a diffusing nutrient field that drives diffusion-limited, branching colony-front expansion.

⚙ Under the hood

Watch a bacterial colony grow across a nutrient-diffusing petri dish. Colony population follows logistic growth while the advancing front branches into dendritic, diffusion-limited patterns wherever local nutrient runs low. Adjust nutrient concentration, growth rate, and diffusion rate to see smooth disk growth turn into fractal branching.
