tinygraphio

Python implementation of the tinygraphio graph data interchange file format.

Installation

Install with poetry

poetry add tinygraphio

Install with pip

pip install tinygraphio

Usage

• The Tinygraph class implements a compressed sparse row graph
• The TinygraphioReader implements reading a graph from a binary file-like object
• The TinygraphioWriter implements writing a graph to a binary file-like object

from tinygraphio.graph import Tinygraph, Node, Edge
from tinygraphio.reader import TinygraphioReader
from tinygraphio.writer import TinygraphioWriter

Writing

graph = Tinygraph(offsets=[0, 2, 4, 5], targets=[1, 2, 0, 2, 1])

with open("berlin.tinygraph", "wb") as f:
    writer = TinygraphioWriter(f)
    writer.write(graph)

Reading

with open("berlin.tinygraph", "rb") as f:
    reader = TinygraphioReader(f)
    graph = reader.read()

Note: this library implements reading and writing a compressed sparse row graph in a The use case tinygraphio covers is storing large graphs effectively and efficiently and sharing graphs in a portable way. We do not provide a full-blown graph computation toolkit on purpose.
