Showing Arbitrary Graph Nodes and Edges for a Network in GraphViz

Question
I'd like to draw a network, as a fully connected directed graph, with arbitrary number of nodes and edges as shown in the pic.
What would be the easy way to draw this with GraphViz?
Solution
graphviz gallery has a very similar entry, with fancy graphic: it's as easy as replacing the names start
, etc... with your own in the generating script. Feed it to dot
program.
digraph G {bgcolor="red:cyan" gradientangle=0
subgraph cluster_0 {
style=filled;
color=lightgrey;
fillcolor="blue:yellow";
gradientangle=90;
node [fillcolor="yellow:green" style=filled gradientangle=270] a0;
node [fillcolor="green:red"] a1;
node [fillcolor="red:cyan"] a2;
node [fillcolor="cyan:blue"] a3;
a0 -> a1 -> a2 -> a3;
label = "process #1";
}
subgraph cluster_1 {
node [fillcolor="yellow:magenta"
style=filled gradientangle=270] b0;
node [fillcolor="magenta:cyan"] b1;
node [fillcolor="cyan:red"] b2;
node [fillcolor="red:blue"] b3;
b0 -> b1 -> b2 -> b3;
label = "process #2";
color=blue
fillcolor="blue:yellow";
style=filled;
gradientangle=90;
}
start -> a0;
start -> b0;
a1 -> b3;
b2 -> a3;
a3 -> a0;
a3 -> end;
b3 -> end;
start [shape=Mdiamond ,
fillcolor="yellow:brown",
gradientangle=90,
style=radial];
end [shape=Msquare,
fillcolor="orange:blue",
style=radial,
gradientangle=90];
}
