Draw Self-loops in Networkx

[satyam]

Is there a way to draw self-loops in Networkx. I don't see it in the
current version of networkx.

Thanks

Unfortunately not. But we are working on improving the drawing and
will add self-loops.

Until then, one approach is to use graphviz (graphviz.org). NetworkX
can write "dot" format files and then you can process them to make the
drawing you like with graphviz.

Thanks Aric. I found a way to implement this is R.

Loading required package: tcltk
Loading Tcl/Tk interface ... done


Maybe we could create an interface of networkx with R and plot the self loops

Thanks

If you really want to do this with R rather than graphviz, look at the
excellent RPy2 package.

Good luck,
