#' Create a new xgx plot
#'
#' @param data Default dataset to use for plot. If not already a data.frame, 
#' will be converted to one by fortify.
#' @param mapping As in ggplot2; Default list of aesthetic mappings to use 
#' for plot. Must define x, y, and group for xgx_spaghetti.
#' @param ... Other arguments passed on to methods. Not currently used. 
#' @param environment If an variable defined in the aesthetic mapping is not 
#' found in the data, ggplot will look for it in this environment. It defaults 
#' to using the environment in which \code{\link[ggplot2]{ggplot}} is called.
