#' Grid1 Graph from AG-Monien Graph Collection
#'
#' This dataset represents the "grid1" graph sourced from the AG-Monien Graph Collection,
#' a collection of test graphs provided by Ralf Diekmann and Robert Preis.
#' The AG-Monien collection encompasses graphs from various origins, including the Harwell-Boeing collection, NASA matrices, and other graphs.
#'
#' @format list of 3 elements
#' \itemize{
#'   \item \code{xy}: A matrix with the coordinates for each node in the graph.
#'   \item \code{sA}: A sparse matrix representation of the graph's adjacency matrix.
#'   \item \code{dim}: A numeric vector containing the numbers of rows, columns, and numerically nonzero elements in the adjacency matrix.
#'   \item \code{temp}: empty list (the path to the temporary directory where the matrix and downloaded files from \code{\link{download_graph}} function).
#'   \item \code{info}: \code{info}: Additional information about the graph.
