This Demonstration gives a glimpse of the development process of leaf venation. Here, the venation is regarded as a transport network and all possible veins are built in advance. Our belief is simple: veins with higher usage are more important so they should grow; on the contrary, veins with lower usage are less important so they should shrink. Visually speaking, the thickness and transparency of individual veins will change during the simulation.
