Re: [igraph] grid graphs

[Tamás Nepusz]

Thank you. How can I then persuade igraph to plot the graph on a 2d

grid maintaining the original position of the nodes?

>>> layout = [index_to_grid_coords(i) for i in xrange(g.vcount())]

>>> plot(g, layout=layout)

Explanation: the layout=… keyword argument of plot() simply expects a Layout object or a list of (x, y) coordinates, one for each vertex in the graph. I simply construct such a list using the index_to_grid_coords() function and then pass that to plot() as the layout keyword.
