ubergraph 0.0.2

A wrapper around pygraphviz to implement an ubergraph

Ubergraph

This is a package used to wrap pygraphviz to create ubergraphs.

Ubergraphs are based upon the paper.

Importing ubergraph

from ubergraph import ubergraph

Functions

Create an ubergraph

You can create an ubergraph which is simply a directed graph in pygraphviz.

u = ubergraph.ubergraph()

Add a node to the ubergraph

You can add nodes to your ubergraph.

u = ubergraph.add_node(u, "node")

Add an edge to the ubergraph

You can add edges to your ubergraph. The lists may be empty. Any undefined nodes or edges will be added to the ubergraph.

u = ubergraph.add_edge(u, "edge", list_of_from_nodes, list_of_to_nodes, list_of_from_edges, list_of_to_edges)

Get the nodes in the ubergraph

You can get the nodes in your ubergraph.

nodes = ubergraph.get_nodes(u)

Get the edges in the ubergraph

You can get the edges in your ubergraph.

edges = ubergraph.get_edges(u)

MAY BE BUGGY: Get the nodes and edges from a node or edge

froms = get_from(u, node_or_edge)

MAY BE BUGGY: Get the nodes and edges to a node or edge

tos = get_to(u, node_or_edge)

MAY BE BUGGY: Get the edges that a node or edge is in

in_edges = get_in_edges(u, node_or_edge)

MAY BE BUGGY: Get the edges that is in a node or edge

out_edges = get_out_edges(u, node_or_edge)

View our ubergraph

Because our ubergraph, u, is a pygraphviz object we can view it by setting the layout (one of https://graphviz.org/docs/layouts/) and then drawing it:

u.layout("circo") # could be other layouts from https://graphviz.org/docs/layouts/
u.draw("filename.png")
