graph 
The input graph. 
dist 
The distance matrix for the multidimensional scaling. If

This is currently ignored, as ARPACK is not used any more for solving the eigenproblem

Passed to 
layout_with_mds
uses metric multidimensional scaling for generating the
coordinates. Multidimensional scaling aims to place points from a higher
dimensional space in a (typically) 2 dimensional plane, so that the distance
between the points are kept as much as this is possible.
By default igraph uses the shortest path matrix as the distances between the
nodes, but the user can override this via the dist
argument.
This function generates the layout separately for each graph component and
then merges them via merge_coords
.
A numeric matrix with dim
columns.
