Overview of this book

Neo4j, along with its Graph Data Science (GDS) library, is a complete solution to store, query, and analyze graph data. As graph databases are getting more popular among developers, data scientists are likely to face such databases in their career, making it an indispensable skill to work with graph algorithms for extracting context information and improving the overall model prediction performance. Data scientists working with Python will be able to put their knowledge to work with this practical guide to Neo4j and the GDS library that offers step-by-step explanations of essential concepts and practical instructions for implementing data science techniques on graph data using the latest Neo4j version 5 and its associated libraries. You’ll start by querying Neo4j with Cypher and learn how to characterize graph datasets. As you get the hang of running graph algorithms on graph data stored into Neo4j, you’ll understand the new and advanced capabilities of the GDS library that enable you to make predictions and write data science pipelines. Using the newly released GDSL Python driver, you’ll be able to integrate graph algorithms into your ML pipeline. By the end of this book, you’ll be able to take advantage of the relationships in your dataset to improve your current model and make other types of elaborate predictions.

Discovering the Neo4j Bloom graph application

Neo4j Bloom is distributed by Neo4j and is a professional-looking application to deal with data specifically stored in a Neo4j database. In this section, we are going to discover its features and use its ability to configure node display color based on a property to visualize graph communities.

What is Bloom?

What can Bloom do for us? It can do all of the following:

  • Graph querying:
    • By label
    • By path
    • With a parametrized Cypher query
  • Graph visualization:
    • Filtered nodes, customized sizes, color, displayed properties, and so on
  • Graph editing:
    • Adding nodes and relationships
    • Adding/editing properties
  • Graph exploration:
    • Shortest path
    • GDS integration

In this chapter, I’ll leave apart the graph editing functionalities to focus on graph querying and graph data visualization features, taking a small tour of the GDS integration.
