Use this if you are using igraph from R
A layout generator for larger graphs.
layout_with_lgl(graph, maxiter = 150, maxdelta = vcount(graph), area = vcount(graph)^2, coolexp = 1.5, repulserad = area * vcount(graph), cellsize = sqrt(sqrt(area)), root = NULL) with_lgl(...)
graph 
The input graph 
maxiter 
The maximum number of iterations to perform (150). 
maxdelta 
The maximum change for a vertex during an iteration (the number of vertices). 
area 
The area of the surface on which the vertices are placed (square of the number of vertices). 
coolexp 
The cooling exponent of the simulated annealing (1.5). 
repulserad 
Cancellation radius for the repulsion (the 
cellsize 
The size of the cells for the grid. When calculating the
repulsion forces between vertices only vertices in the same or neighboring
grid cells are taken into account (the fourth root of the number of

root 
The id of the vertex to place at the middle of the layout. The default value is 1 which means that a random vertex is selected.

Passed to 
layout_with_lgl
is for large connected graphs, it is similar to the layout
generator of the Large Graph Layout software
(http://lgl.sourceforge.net/).
A numeric matrix with two columns and as many rows as vertices.
