Development commonly involves an interplay between signaling, genetic expression and biophysical
forces. However, the relative importance of these mechanisms during the different stages of
development is unclear. Leaf venation networks provide a fitting context for the examination of these
questions. In mature leaves, venation patterns are extremely diverse, yet their local structure satisfies a
universal property: at junctions between veins, angles and diameters are related by a vectorial equation
