WebbDetails. In igraph a vertex shape is defined by two functions: 1) provides information about the size of the shape for clipping the edges and 2) plots the shape if requested. These functions are called “shape functions” in the rest of this manual page. The first one is the clipping function and the second is the plotting function.
