\title{Place nodes in circles according to centrality measure}
\usage{
layout_tbl_graph_centrality(
graph,
centrality,
scale = TRUE,
niter = 500,
tolerance = 1e-04,
tseq = seq(0, 1, 0.2),
group = NULL,
shrink = 10,
circular = FALSE
)
}
\arguments{
\item{graph}{A tbl_graph object}
\item{centrality}{An expression evaluating to a centrality measure for the
nodes. See the different \verb{centrality_*()} algorithms in tidygraph for a
selection.}
\item{scale}{Should the centrality measure be scaled between 0 and 100}
\item{niter}{number of iterations during stress optimization}
\item{tolerance}{stopping criterion for stress optimization}
\item{tseq}{Transitioning steps}
\item{group}{An expression evaluating to a grouping of the nodes. If given
the layout will keep grouped nodes within an angle range of the origin}
\item{shrink}{shrink the reserved angle range for a group to increase the
gaps between groups}
\item{circular}{ignored}
}
\value{
A data.frame with the columns \code{x}, \code{y}, \code{circular}, \code{centrality} as
well as any information stored as node variables in the tbl_graph object.
}
\description{
This layout places nodes in circles with the radii relative to a given
centrality measure. Under the hood it use stress majorisation to place nodes
optimally given the radius constraint.
