\alias{layout_tbl_graph_matrix}
\title{Place nodes on a diagonal}
\usage{
layout_tbl_graph_matrix(graph, circular = FALSE, sort.by = NULL)
}
\arguments{
\item{graph}{An \code{tbl_graph} object}
\item{circular}{Ignored}
\item{sort.by}{An expression providing the sorting of the nodes. If \code{NULL}
the nodes will be ordered by their index in the graph.}
}
\value{
A data.frame with the columns \code{x}, \code{y}, \code{circular} as
well as any information stored as node variables in the tbl_graph object.
}
\description{
This layout puts all nodes on a diagonal, thus preparing the layout for use
with \code{\link[=geom_edge_point]{geom_edge_point()}} resulting in a matrix layout. While matrix
layouts excel in scalability, the interpretation of the visual is very
dependent on the sorting of the nodes. Different sorting algorithms have been
implemented in \code{tidygraph} and these can be used directly. Behrisch
\emph{et al.} (2016) have provided a nice overview of some of the different
sorting algorithms and what insight they might bring, along with a rundown of
different patterns to look out for.
