Neo4j¶

Neo4j is a graph database, and is useful when the relationships between items in our database is of interest.

Graph concepts¶

elements¶

graph
vertex
edge
path

graph properties¶

directed or undirected
weighted or unweighted
cyclic or acyclic
single or multiple edges
connected or disconnected

vertex properties¶

in-degree
out-degree
centrality

edge properties¶

direction
weight
multiplicity

Graph representations¶

Vertex and edge collections
Adjacency list
Adjacency matrix
Sparse matrix

In [38]:

vs = ['a', 'b', 'c', 'd']
es = [('a','c', 1), ('b','c', 2), ('a','d', 3), ('c', 'd', 4)]

g1 = nx.DiGraph()
g1.add_nodes_from(vs)
g1.add_weighted_edges_from(es)

pos = nx.spring_layout(g1)
labels = nx.get_edge_attributes(g1,'weight')
nx.draw(g1, pos=pos, alpha=0.5)
nx.draw_networkx_edge_labels(g1, pos=pos, edge_labels=labels)
nx.draw_networkx_labels(g1, pos=pos)
pass

In [57]:

import sys

In [59]:

nx.write_adjlist(g1, sys.stdout)

#/usr/local/lib/python3.6/site-packages/ipykernel_launcher.py -f /Users/cliburn/Library/Jupyter/runtime/kernel-c9a57054-1320-4816-9dbe-da7c9fc8eeb8.json

In [73]:

print(nx.adj_matrix(g1))

  (0, 2)        1
  (0, 3)        3
  (1, 2)        2
  (2, 3)        4

In [72]:

nx.adj_matrix(g1).todense()

Out[72]:

        [0, 0, 0, 4],

Standard format for graph exchange is GraphML¶

In [60]:

nx.write_gml(g1, sys.stdout)

graph [
  directed 1
  node [
    id 0
    label "a"
  ]
  node [

    label "b"
  ]
  node [
    id 2
    label "c"
  ]
  node [
    id 3
    label "d"
  ]
  edge [
    source 0
    target 2
    weight 1
  ]
  edge [
    source 0
    target 3
    weight 3
  ]
  edge [
    source 1
    target 2
    weight 2
  ]
  edge [
    source 2
    target 3
    weight 4
  ]
]

Some examples¶

In [1]:

import networkx as nx

In [3]:

n = 50
k = 6
p =0.3
g = nx.watts_strogatz_graph(n, k, p)

In [21]:

%matplotlib inline

Visual representations of the same graph may look very different¶

Complete graph¶

In [25]:

nx.draw_circular(nx.complete_graph(10), alpha=0.5)

In [26]:

nx.draw(nx.complete_graph(10), alpha=0.5)

In [27]:

nx.draw_random(nx.complete_graph(10), alpha=0.5)

Undirected graph¶

In [14]:

nx.draw(nx.krackhardt_kite_graph(), alpha=0.5)

Directed graph¶

In [29]:

nx.draw(nx.gn_graph(25), alpha=0.5)

Cypher¶

In [2]:

%load_ext cypher

In [3]:

%config CypherMagic.uri='http://neo4j:bios-823@localhost:7474/db/data/'

Create a database¶

This is a small subset of the full database. If you want to play with the full database, see instructions

Note: There are other ways to create a graph database by importing data
