An optimized graphs package for the Julia programming language
LightGraphs offers both (a) a set of simple, concrete graph implementations --
Graph(for undirected graphs) and
DiGraph(for directed graphs), and (b) an API for the development of more sophisticated graph implementations under the
The project goal is to mirror the functionality of robust network and graph analysis libraries such as NetworkX while being simpler to use and more efficient than existing Julian graph libraries such as Graphs.jl. It is an explicit design decision that any data not required for graph manipulation (attributes and other information, for example) is expected to be stored outside of the graph structure itself. Such data lends itself to storage in more traditional and better-optimized mechanisms.
Additional functionality may be found in a number of companion packages, including: * LightGraphsExtras.jl: extra functions for graph analysis. * MetaGraphs.jl: graphs with associated meta-data. * SimpleWeightedGraphs.jl: weighted graphs. * GraphIO.jl: tools for importing and exporting graph objects using common file types like edgelists, GraphML, Pajek NET, and more.
Installation is straightforward: enter Pkg mode by hitting
