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 AbstractGraph
type.
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.
Full documentation is available at GitHub Pages. Documentation for methods is also available via the Julia REPL help system. Additional tutorials can be found at JuliaGraphsTutorials.
Installation is straightforward:
julia> Pkg.add("LightGraphs")- LightGraphs master is designed to work with the latest stable version of Julia.
- Julia 0.3: LightGraphs v0.3.7 is the last version guaranteed to work with Julia 0.3.
- Julia 0.4: LightGraphs versions in the 0.6 series are designed to work with Julia 0.4.
- Julia 0.5: LightGraphs versions in the 0.7 series are designed to work with Julia 0.5.
- Julia 0.6: LightGraphs versions in the 0.8 through 0.11 series are designed to work with Julia 0.6.
- Later versions: Some functionality might not work with prerelease / unstable / nightly versions of Julia. If you run into a problem, please file an issue.
We welcome contributions and bug reports! Please see CONTRIBUTING.md for guidance on development and bug reporting.
