This package collects I/O utilities for algebraic-graphs : parsers and serializers for common graph data interchange formats, as well as functionality for downloading and caching larger datasets.

Currently the following formats are supported :

• GML : used by a few common graph software packages (NetworkX, Gephi, graphviz, and others)

• .tsv : tab-separated list of edge data, used e.g. for the Graph Challenge dataset [1]

• JSON : via 'aeson'

• CBOR : via 'serialise'

The package contains some small example datasets (e.g. "lesmiserables" and "karateclub"); these are provided ready for consumption in Algebra.Graph.IO.Datasets.

There are also bindings to larger datasets, such as the ones provided by the LINQS group [2] (e.g. "citeseer" and "cora").
