graph-notebook 3.4.0

jupyter notebook extension to connect to graph databases

Graph Notebook: easily query and visualize graphs

The graph notebook provides an easy way to interact with graph databases using Jupyter notebooks. Using this open-source Python package, you can connect to any graph database that supports the Apache TinkerPop, openCypher or the RDF SPARQL graph models. These databases could be running locally on your desktop or in the cloud. Graph databases can be used to explore a variety of use cases including knowledge graphs and identity graphs.

Visualizing openCypher queries

Visualizing SPARQL queries:

Instructions for connecting to the following graph databases:

Endpoint	Graph model	Query language
Gremlin Server	property graph	Gremlin
Blazegraph	RDF	SPARQL
Amazon Neptune	property graph or RDF	Gremlin or SPARQL

We encourage others to contribute configurations they find useful. There is an additional-databases folder where more information can be found.

Features

Notebook cell 'magic' extensions in the IPython 3 kernel

%%sparql - Executes a SPARQL query against your configured database endpoint.

%%gremlin - Executes a Gremlin query against your database using web sockets. The results are similar to those a Gremlin console would return.

%%opencypher or %%oc Executes an openCypher query against your database.

%%graph_notebook_config - Sets the executing notebook's database configuration to the JSON payload provided in the cell body.

%%graph_notebook_vis_options - Sets the executing notebook's vis.js options to the JSON payload provided in the cell body.

%%neptune_ml - Set of commands to integrate with NeptuneML functionality. Documentation

TIP :point_right: There is syntax highlighting for %%sparql, %%gremlin and %%oc cells to help you structure your queries more easily.

TIP :point_right: Many of the magic commands support a --help option in order to provide additional information.

Example notebooks

This project includes many example Jupyter notebooks. It is recommended to explore them. All of the commands and features supported by graph-notebook are explained in detail with examples within the sample notebooks. You can find them here. As this project has evolved, many new features have been added. If you are already familiar with graph-notebook but want a quick summary of new features added, a good place to start is the Air-Routes notebooks in the 02-Visualization folder.

Keeping track of new features

It is recommended to check the ChangeLog.md file periodically to keep up to date as new features are added.

Prerequisites

You will need:

• Python 3.6.13-3.9.7
• RDFLib 5.0.0
• A graph database that provides one or more of:
  • A SPARQL 1.1 endpoint
  • An Apache TinkerPop Gremlin Server compatible endpoint
  • An endpoint compatible with openCypher

Installation

Begin by installing graph-notebook and its prerequisites, then follow the remaining instructions for either Jupyter Classic Notebook or JupyterLab.

# pin specific versions of required dependencies
pip install rdflib==5.0.0
pip install markupsafe==2.0.1

# install the package
pip install graph-notebook

Jupyter Classic Notebook

# install and enable the visualization widget

# ONLY RUN THIS LINE IF USING graph-notebook<=3.2.0
jupyter nbextension install --py --sys-prefix graph_notebook.widgets

jupyter nbextension enable  --py --sys-prefix graph_notebook.widgets

# copy static html resources
python -m graph_notebook.static_resources.install
python -m graph_notebook.nbextensions.install

# copy premade starter notebooks
python -m graph_notebook.notebooks.install --destination ~/notebook/destination/dir

# create nbconfig file and directory tree, if they do not already exist
mkdir ~/.jupyter/nbconfig
touch ~/.jupyter/nbconfig/notebook.json

# start jupyter notebook
python -m graph_notebook.start_notebook --notebooks-dir ~/notebook/destination/dir

JupyterLab 3.x

# install jupyterlab
pip install "jupyterlab>=3"

# copy premade starter notebooks
python -m graph_notebook.notebooks.install --destination ~/notebook/destination/dir

# start jupyterlab
python -m graph_notebook.start_jupyterlab —-jupyter-dir ~/notebook/destination/dir

Loading magic extensions in JupyterLab

When attempting to run a line/cell magic on a new notebook in JupyterLab, you may encounter an error like:

UsageError: Cell magic `%%graph_notebook_config` not found.

To fix this, manually reload the magic extensions by running:

%load_ext graph_notebook.magics

Connecting to a graph database

Gremlin Server

In a new cell in the Jupyter notebook, change the configuration using %%graph_notebook_config and modify the fields for host, port, and ssl. Optionally, modify traversal_source if your graph traversal source name differs from the default value. For a local Gremlin server (HTTP or WebSockets), you can use the following command:

%%graph_notebook_config
{
  "host": "localhost",
  "port": 8182,
  "ssl": false,
  "gremlin": {
    "traversal_source": "g"
  }
}

To setup a new local Gremlin Server for use with the graph notebook, check out additional-databases/gremlin server

Blazegraph

Change the configuration using %%graph_notebook_config and modify the fields for host, port, and ssl. For a local Blazegraph database, you can use the following command:

%%graph_notebook_config
{
  "host": "localhost",
  "port": 9999,
  "ssl": false,
  "sparql": {
    "path": "sparql"
  }
}

You can also make use of namespaces for Blazegraph by specifying the path graph-notebook should use when querying your SPARQL like below:

%%graph_notebook_config

{
  "host": "localhost",
  "port": 9999,
  "ssl": false,
  "sparql": {
    "path": "blazegraph/namespace/foo/sparql"
  }
}

This will result in the url localhost:9999/blazegraph/namespace/foo/sparql being used when executing any %%sparql magic commands.

To setup a new local Blazegraph database for use with the graph notebook, check out the Quick Start from Blazegraph.

Amazon Neptune

Change the configuration using %%graph_notebook_config and modify the defaults as they apply to your Neptune cluster:

%%graph_notebook_config
{
  "host": "your-neptune-endpoint",
  "port": 8182,
  "auth_mode": "DEFAULT",
  "load_from_s3_arn": "",
  "ssl": true,
  "aws_region": "your-neptune-region"
}

To setup a new Amazon Neptune cluster, check out the Amazon Web Services documentation.

When connecting the graph notebook to Neptune, make sure you have a network setup to communicate to the VPC that Neptune runs on. If not, you can follow this guide.

Authentication (Amazon Neptune)

If you are running a SigV4 authenticated endpoint, ensure that your configuration has auth_mode set to IAM:

%%graph_notebook_config
{
  "host": "your-neptune-endpoint",
  "port": 8182,
  "auth_mode": "IAM",
  "load_from_s3_arn": "",
  "ssl": true,
  "aws_region": "your-neptune-region"
}

Additionally, you should have the following Amazon Web Services credentials available in a location accessible to Boto3:

• Access Key ID
• Secret Access Key
• Default Region
• Session Token (OPTIONAL. Use if you are using temporary credentials)

These variables must follow a specific naming convention, as listed in the Boto3 documentation

A list of all locations checked for Amazon Web Services credentials can also be found here.
