Tverberg's theorem says that a set with sufficiently many points in R^d can always be partitioned into m parts so that the (m-1)-simplex is the (nerve) intersection pattern of the convex hulls of the parts. The main results of our paper demonstrate that Tverberg's theorem is but a special case of a more general situation. Given sufficiently many points, all trees and cycles can also be induced by at least one partition of a point set.
