GraphIO provides support to Graphs.jl for reading/writing graphs in various formats.
Currently, the following functionality is provided:
| Format | Read | Write | Multiple Graphs | Format Name |
|---|---|---|---|---|
| [EdgeList] | ✓ | ✓ | EdgeListFormat | |
| [GML] | ✓ | ✓ | ✓ | GMLFormat |
| [Graph6] | ✓ | ✓ | ✓ | Graph6Format |
| [GraphML] | ✓ | ✓ | ✓ | GraphMLFormat |
| [Pajek NET] | ✓ | ✓ | NETFormat | |
| [GEXF] | ✓ | GEXFFormat | ||
| [DOT] | ✓ | ✓ | DOTFormat | |
| [CDF] | ✓ | CDFFormat |
[EdgeList]: a simple list of sources and dests separated by whitespace and/or comma, one pair per line.

Graphs are read using either the loadgraph function or, for formats that support multiple graphs in a single file,
the loadgraphs functions. loadgraph returns a Graph object, while loadgraphs returns a dictionary of Graph objects.
For example, an edgelist file could be loaded as:
graph = loadgraph("path_to_graph/my_edgelist.txt", "graph_key", EdgeListFormat())
