Dot Graph Examples

Triangle

A triangle with large margins

```text only digraph A {

rankdir=LR; center=true; margin=1; nodesep=1.5; ranksep=0.5;

node [shape=point, height=”.2”, width=”.2”];

a [xlabel=”a”]; b [xlabel=”b”]; c [xlabel=”c”]; a -> b -> c; a -> c; }

### Label + XLabel
```text only
digraph A {

  rankdir=LR;
  center=true; margin=1; 
  nodesep=1.5; ranksep=1.5;

  node [height="0.5", width="0.5", fixedsize=true];
  
  X [xlabel=100];
  Y [xlabel=150];
  I1 [xlabel=150];
  I2 [xlabel=100];
  {X, Y}->{I1, I2};

}

```text only digraph A { rankdir=LR; center=true; margin=1;

node [height=”0.33”, width=”0.33”, fixedsize=true];

b->a->d->g; a->e->h; e->g; d->{c,f};

c->e [dir=”back”]; g->h [dir=”back”];

b,d,e [style=filled, fillcolor=red, peripheries=2];

{rank=same; f;g;h;} {rank=same; d;e;c;} {rank=same; a;b;} }

### Neato Example
```text only
graph G {
  nodesep=1.5;
  center=true; margin=1; 
  node [color=black, shape=rectangle, style="filled", fillcolor=skyblue];
  edge [len=2];
  a;b;c;d;e;
  a--{b,c,d,e};
  b--{c,d,e};
  c--{d,e};
  d--e;
}

```text only digraph G { rankdir=LR; nodesep=0.7; ranksep=1; node [shape=none, fixedsize=true, width=0.3];

a->b->d; a->c->d; b->c [color=”black:white:black”,dir=none]; a->e->d; c->e [style=invis]; {rank=same;b;c;e;} } ```
