  abstract = {Euler diagrams are common and user-friendly visualizations
    for set relationships. Most Euler diagrams use circles, but circles
    do not always yield accurate diagrams. A promising alternative is
    ellipses, which, in theory, enable accurate diagrams for a wider
    range of input. Elliptical diagrams, however, have not yet been
    implemented for more than three sets or three-set diagrams where
    there are disjoint or subset relationships. The aim of this paper is
    to present eulerr: a software package for elliptical Euler diagrams
    for, in theory, any number of sets. It fits Euler diagrams using
    numerical optimization and exact-area algorithms through a two-step
    procedure, first generating an initial layout using pairwise
    relationships and then finalizing this layout using all set
    relationships. container-title: Proceedings of International
