Graphs may be written to I/O streams and files using the
savegraph function and read with the
loadgraph function. The default graph format is a bespoke compressed LightGraphs.jl format
g = erdos_renyi(5, 0.2) savegraph("mygraph.lgz", g) reloaded_g = loadgraph("mygraph.lgz")
In addition, graphs can also be saved in an uncompressed format using the
savegraph("mygraph.lg", g, compress=false) reloaded_g = loadgraph("mygraph.lg")
Finally, dictionaries of graphs can also be saved and subsequently re-loaded one by one.
graph_dict = Dict("g1" => erdos_renyi(5, 0.1), "g2" => erdos_renyi(10, 0.2), "g3" => erdos_renyi(2, 0.9)) savegraph("mygraph_dict.lg", graph_dict) # Re-load only graph g1 reloaded_g1 = loadgraph("mygraph_dict.lg", "g1")
The GraphIO.jl library provides tools for importing and exporting graph objects using common file types like edgelists, GraphML, Pajek NET, and more.
