A quick visualization tool for Jupyter and Neo4J

neo4jupyter

A tool to visualize graph database queries from Neo4j in the Jupyter Notebook.

Install

pip install neo4jupyter

Docs

First thing you must do is call the neo4jupyter.init_notebook_mode() to load all the javascript.

import neo4jupyter
neo4jupyter.init_notebook_mode()

Drawing a graph it's as easy as giving the funcion neo4jupyter.draw() the py2neo graph object and the parameters that you want to be displayed. An example of the settings for the movie graph tutorial, options = {"Movie": "title", "Person": "name"} will show the nodes Person and Movie by title and name consecutively and their connexions.

neo4jupyter.draw(graph_object_py2neo, {"Nodes_type": "Att", …})

I encourage you to read the neo4jupyter.py file, is small and subject to be enhanced.

neo4jupyter's Issues

Export as an html file

Is there any way to export the result on jupyter notebook as html？I need it badly and I would really appreciate it if this can be solved

Suggestion for handling subgraphs

I have need of presenting a subgraph (py2neo.Subgraph) and this package is close to what I would like to do. (thank you for publishing it on github) Have code to enhance to present subgraph in cases where you want to show what will be merged or want to select a subset of nodes out of a graph for presentation. Are you interested in taking new pull requests? (i'm new to that process, but thought I would give it a go if you're interested.)

Example code of proposed function draw_subgraph

from py2neo import Graph, Node, Relationship, NodeSelector, Subgraph, remote
import neo4jupyter
import vis
neo4jupyter.init_notebook_mode()
class Knows(Relationship): pass
class Dates(Relationship): pass
class Despises(Relationship): pass
class Person(Node): pass
sam = Node('Person', Name = 'Sam')
bob = Node('Person', Name = 'Bob')
george = Node('Person', Name = 'George')
suzy = Node('Person', Name = 'Suzy')

sg = Knows(bob, sam)
sg |= Knows(sam, suzy) 
sg |= Dates(bob, suzy)
sg |= Despises(george, bob)
neo4jupyter.draw_subgraph(sg, options = {"Person": "Name"})`

Jupyter Lab: neo4jupyter.init_notebook_mode() -> Javascript Error: require is not defined

neo4jupyter (v 0.1.2) doesn't seem to work in Jupyter Lab:

import neo4jupyter
neo4jupyter.init_notebook_mode()

Javascript Error: require is not defined

TypeError: 'LabelSetView' object is not callable

I get this error when running the code against a Neo4j 3.4.0 db and V4.X of Py2Neo Library.

It has to be a version issue, any suggestions?

Automate the init_notebook_mode

Automatically run on draw() if it's not been previously runned.

'SetView' object is not callable

Facing issue when using draw_subgraph
'SetView' object is not callable

physics

Hi

Is there a way to change, adapt the physics, by passing parameters? This would be great for my use case, but I didn't manage to do it. Somehow the code looks like there are DEFAULT_PHYSICS but changing this constant, had no influence on the output.

Secondly, I wrote an adapted function to use neo4jupyter with the python graph data science package (gds.run_cypher). If you are interested, I would love to commit the code.

Thank you!

TypeError: 'LabelSetView' object is not callable

This error comes up when I try to execute neo4jupyter.draw
(from the demo code).

TypeError: 'LabelSetView' object is not callable

I thought this was solved, but it does not actually seem to be.
Is there a chance that a newer version of py2neo has a breaking change?

It seems to have something to do with the labels attribute. In fact... the query in neo4jupyter.py does not seem to be actually returning any objects (not sure the proper terminology here):
