Graph Formats
Program-Transformation.Org: The Program Transformation Wiki
Graph drawing and editing tools typically have their own graph
specification format. The format has typically a textual
representation that is easy to read and write. The benefits of this
approach are twofold. Humans can write their own graph specification
directly in the graph format (without necessarily using a graph
editing tool) and tools can easily generate and parse graph data. On
the downside, these formats are not space efficient. Graph formats
share the following characteristics: (1) Expression of arbitrary
graphs, (2) distinction between nodes and edges, and (3) attribution
of nodes and edges.
