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:

  • Node
  • Edge
  • Graph
    (I.e. a subgraph is specified in the same manner a top-level graph is specified. There is no special keyword for subgraphs.)
  • Region
  • Graph attribute

The delimiter between items of a list is one or more whitespace characters (spaces, tabs, line feeds, carriage returns). There is no order required for nodes, edges, subgraphs or attributes. However, depending on the layout algorithm selected, the order of nodes may influence the final layout (see rank assignment).

Node format

A node is specified by

node: { title: "node title"
        other node attributes }

The title of a node is any valid C string. It may contain the normal C escapes (e.g. \n, \t, \", ...) and special characters of the ISO Latin 1 set.
