Network Layouting in R

Hi,



I am trying to plot a network diagram of around 1500 component (as nodes)
and many connections (as edges) within them.

I tried igraph package, however unable to create a layout where there is no
overlap of nodes or edges.

How do you know it's physically possible to create a 2D layout with no overlap?
1500 nodes is a lot.

What did you try? What did you get? Did you produce a diagram, just
with more overlap than you were expecting? That may be the best you
can do.

More or less tried all the things mentioned in this link -

http://kateto.net/network-visualization

Again, what did you try? What did you get that doesn't meet your
needs? Just the overlap? Again, that may be unavoidable. Note the
comment from that link:
"One thing to emphasize though is that in many cases, visualizing
larger networks as giant hairballs is less helpful than providing
charts that show key characteristics of the graph."

Can you please suggest how to do it in R ?

For working with largish graph layouts, I've had more success with
gephi than R, although I believe you can duplicate most of the gephi
functionality in R.

Output expected ? A good layout of the network diagram (of around 1500
nodes) with no overlaps of nodes or even edges and possibly it can be
screened as a picture, or on a browser or on a pdf.
