Need help with network diagram example

Dear All,

can somebody help me to reproduce the example from Gallery. I need namely circles with nodes on them.

I mean this one: A Network Map | Graphviz

I tried a lot of different parameters but cannot see that beautiful circle, but only some mesh of nodes.

Regards.

Were you using the twopi layout engine (twopi | Graphviz)?

The source for the network graph is here: https://graphviz.org/Gallery/twopi/twopi2.gv.txt
simple command line is twopi -Tsvg -o net.svg twopi2.gv

You might also look at:
circo (circo | Graphviz)
and
my radial preprocessor (A radial Graphviz engine (pre-processor))

Thanks a lot. The parameter -Goverlap was wrong in my case.
