displayNet -- displays a chordal network using Graphivz



Displays a chordal network using Graphviz.

The text displayed in each of the nodes can be provided by the optional input label. The default is label:= net.


Consider the following chordal network.
i1 : R = QQ[a..e,MonomialOrder=>Lex];
i2 : I = ideal {a*b, b*c, c*d, a*e, d*e};

o2 : Ideal of R
i3 : N = chordalNet I;
i4 : chordalTria N;
i5 : topComponents N;
i6 : N

o6 = ChordalNet{ a => {a,  }       }
                 b => {b,  , b}
                 c => { , c, c,  }
                 d => {d,  , d}
                 e => { , e}

o6 : ChordalNet
The command displayNet N outputs the following figure.
