#' @description Show a graph representation of the game board with nodes placed in the appropriate relative spot, colored by the number of paths which include a particular node. Possible hideouts are marked with blue squares.
#'
#' @param paths optional list of all possible paths already traveled
#' @param hideouts optional vector of possible hideouts from previous rounds.
#' @param roads data.frame of non-directional edge pairs for the road graph
#' @param alley data.frame of non-directional edge pairs for the alley graph

#' @details
#' roads, alley and node_locations are all bundled with the package (e.g. \code{data(roads)}).
#' Solid lines in the graph represent road connections between nodes. Dashed lines represent alley way connections.
