Unix lineage

One of the stock examples of graphviz is the Unix lineage. In this notebook we'll be visualizing that graph using DAGVIZ.

Construct the graph

import networkx as nx
from dagviz import Dagre, Metro

u = nx.DiGraph()
u.add_edge('5th Edition', '6th Edition')
u.add_edge('5th Edition', 'PWB 1.0')
u.add_edge('6th Edition', 'LSX')
u.add_edge('6th Edition', '1 BSD')
u.add_edge('6th Edition', 'Mini Unix')
u.add_edge('6th Edition', 'Wollongong')
u.add_edge('6th Edition', 'Interdata')
u.add_edge('Interdata', 'Unix/TS 3.0')
u.add_edge('Interdata', 'PWB 2.0')
u.add_edge('Interdata', '7th Edition')
u.add_edge('7th Edition', '8th Edition')
u.add_edge('7th Edition', '32V')
u.add_edge('7th Edition', 'V7M')
u.add_edge('7th Edition', 'Ultrix-11')
u.add_edge('7th Edition', 'Xenix')
u.add_edge('7th Edition', 'UniPlus+')
u.add_edge('V7M', 'Ultrix-11')
u.add_edge('8th Edition', '9th Edition')
