to_sparse6_bytes(G, nodes=None, header=True)

Notes

The returned bytes end with a newline character.

The format does not support edge or node labels.

Parameters

G : Graph (undirected)

nodes: list or iterable :

Nodes are labeled 0...n-1 in the order provided. If None the ordering given by G.nodes() is used.

header: bool :

If True add '>>sparse6<<' bytes to head of data.

Raises

NetworkXNotImplemented

If the graph is directed.

ValueError

If the graph has at least 2 ** 36 nodes; the sparse6 format is only defined for graphs of order less than 2 ** 36 .

Convert an undirected graph to bytes in sparse6 format.

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
