The Language

We use The Dot language to describe graphs. You can omit graph Name {} declaration. So that we will guess.

Here is small example: Example Graph

### Water circulation
## by Sample Creator
Water -> ice
Water -> steam
Water -> water
water -> ice [label="freezing"]
steam -> water [label="cooling"]
Water [shape=doublecircle]
{rank = same; ice; water; steam}

Extensions

First line starting with ### is a graph title. First line which starts with ## is author name. They will be displayed above your graph. You can also write comments starting with # they all will be presented under graph while viewing.

Tips and Tricks

Dot has several layout engines, namely dot, neato, twopi, circo, fdp, sfdp. You can experiment with them by writing layout=engine inside your graph. Default is layout=dot.
You can scale your graph by writing size="width, height". It's bounding box of graph and it's in inches. But just experiment with some values.
You can place a label under your graph by writing label="Text"
Experiment with rankdir=LR if your graph is too wide (other values BT, TB, RL)
