\section about_layouts

Layout generator functions (or at least most of them) try to place the vertices and edges of a graph on a 2D plane or in 3D space in a way which visually pleases the human eye.

They take a graph object and a number of parameters as arguments and return an \type igraph_matrix_t, in which each row gives the coordinates of a vertex.
