#' Plant-Pollinator Data Sets in Hive Plot Data Format
#' Plant-pollinator data sets which were derived ultimately from Vasquez and
#' Simberloff, 2003.  These are two-trophic level systems that have almost
#' exactly the same plants and pollinators.  \code{Safari} is from an
#' undisturbed area, while \code{Arroyo} is from a nearby location grazed by
#' cattle.  In the original publication, the data sets are called Safariland
#' and Arroyo Goye.  See Details for how the original data was converted.
#' These data sets are \code{\link{HivePlotData}} objects.  They were created
#' from the datasets \code{Safariland} and \code{vazarr} in the package
#' \code{bipartite}.  The process was the same for each: 1.  Plants were placed
#' on one axis, pollinators on the other.  2.  A radius was assigned by
#' calculating d' using function \code{dfun} in package \code{bipartite}.  d'
#' is an index of specialization; higher values mean the plant or pollinator is
#' more specialized.  3.  Edge weights were assigned proportional to the square
#' root of the normalized number of visits of a pollinator to a plant.  Thus
#' the width of the edge drawn is an indication of the visitation rate.  4.
#' The number of visits were divided manually into 4 groups and used to assign
#' edge colors ranging from white to red.  The redder colors represent greater
#' numbers of visits, and the color-coding is comparable for each data set.
