Small Graph Lib
Installing
Basic installation
Smallgraphlib is on PyPI, so you can download and install it with pip, as any usual python package.
pip install smallgraphlib
Development version
For development, please clone the last version from Github:
git clone https://github.com/wxgeo/smallgraphlib
You will then need uv to manage the development process.
If needed, install it on Linux or Mac with:
curl -LsSf https://astral.sh/uv/install.sh | sh
More information on uv installation
It is also recommended to install just command runner, to execute
the recipes of the justfile.
uv tool install rust-just
Usage
Main classes are Graph, DirectedGraph, WeightedGraph and WeightedDirectedGraph:
>>> from smallgraphlib import DirectedGraph
>>> g = DirectedGraph(["A", "B", "C"], ("A", "B"), ("B", "A"), ("B", "C"))
>>> g.is_simple
True
>>> g.is_complete
False
>>> g.is_directed
True
>>> g.adjacency_matrix
[[0, 1, 0], [1, 0, 1], [0, 0, 0]]
>>> g.degree
3
>>> g.order
3
>>> g.is_eulerian
False
>>> g.is_semi_eulerian
True
Special graphs may be generated using factory functions:
>>> from smallgraphlib import complete_graph, complete_bipartite_graph
>>> K5 = complete_graph(5)
>>> len(K5.greedy_coloring)
5
>>> K33 = complete_bipartite_graph(3, 3)
>>> K33.degree
6
>>> K33.diameter
2
If the graph is not too complex, Tikz code may be generated:
>>> g.as_tikz()
...
