Description: High-dimensional visualization methods for data
        envelopment analysis (DEA), gathering in one place techniques
        that have appeared in the literature but remained scattered and
        largely unimplemented: cross-efficiency matrix unfolding, the
        Porembski network with lambda edges, principal component
        analysis biplots, multidimensional-scaling colour-plots,
        self-organizing maps, the Costa bi-dimensional efficient
        frontier, parallel coordinates, radar charts, panel-data
        trajectory biplots, peer and reference networks, and a set of
        descriptive plots. The package is built around a single
        validated dea_data() object and uses the 'Benchmarking' package
        as its DEA engine. The implemented methods draw on a body of
        literature; representative references include Doyle and Green
        (1994) <doi:10.1057/jors.1994.84>, Porembski, Breitenstein and
        Alpar (2005) <doi:10.1007/s11123-005-1328-5> and Bana e Costa,
        Soares de Mello and Angulo Meza (2016)
