Graph Format
A graph (the top-level graph or a subgraph) is specified by
graph: {
< list of graph_entries >
}
A graph_entry
is one of the following:
- Subgraph,
i.e. a subgraph is specified in the same manner a top-level graph is
specified. There is no special keyword for subgraphs.
- Node
- Edge
- Attribute
- Region
The delimiter between items of a list is one or more whitespace
characters.
There is no order required for nodes, edges, subgraphs or attributes.
However, the order of nodes may influence the final layout.
