This guide shows the different ways you can import data from a relational database to Neo4j. Completing this guide will give you the tools to choose how to import your relational data and transform it to the graph.
You should be familiar with graph database concepts and the property graph model. It is also helpful to know the differences between relational and graph concepts and their data models.

Building Neo4j Applications with Python
In this course, we walk through the steps to integrate Neo4j into your Python projects. We will follow the steps to create an instance of the Neo4j Python Driver, learn about sessions and transactions, and use that knowledge to build a REST API with Flask.

Neovis.js
This library was designed to combine JavaScript visualization and Neo4j in a seamless integration. Connection to Neo4j is simple and straightforward, and because it is built with Neo4j’s property graph model in mind, the data format Neovis expects aligns with the database. Customizing and coloring styles based on labels, properties, nodes, and relationships is defined in a single configuration object. Neovis.js can be used without writing Cypher and with minimal JavaScript for integrating into your project.
The Neovis library is one of our Neo4j Labs projects. To learn more about Neo4j Labs, visit our Labs page. |
To maximize functionality and data analysis capabilities through visualization, you can also combine this library with the graph algorithms library in Neo4j to style the visualization to align with results of algorithms such as page rank, centrality, communities, and more. Below, we see a graph visualization of Game Of Thrones character interactions rendered by neovis.js, and enhanced using Neo4j graph algorithms by applying pagerank and community detection algorithms to the styling of the visualization.
An advantage of enhancing graph visualization with these algorithms is that we can visually interpret the results of these algorithms.

-
The algorithm supports configuration to set node and/or relationship properties to use as weights. These values can represent cost, time, capacity or some other domain-specific properties, specified via the nodeWeightProperty, nodeProperties and relationshipWeightProperty configuration parameters. The algorithm will by default consider each node and/or relationship as equally important.
