Overview of this book

Neo4j is a graph database that includes plugins to run complex graph algorithms. The book starts with an introduction to the basics of graph analytics, the Cypher query language, and graph architecture components, and helps you to understand why enterprises have started to adopt graph analytics within their organizations. You’ll find out how to implement Neo4j algorithms and techniques and explore various graph analytics methods to reveal complex relationships in your data. You’ll be able to implement graph analytics catering to different domains such as fraud detection, graph-based search, recommendation systems, social networking, and data management. You’ll also learn how to store data in graph databases and extract valuable insights from it. As you become well-versed with the techniques, you’ll discover graph machine learning in order to address simple to complex challenges using Neo4j. You will also understand how to use graph data in a machine learning model in order to make predictions based on your data. Finally, you’ll get to grips with structuring a web application for production using Neo4j. By the end of this book, you’ll not only be able to harness the power of graphs to handle a broad range of problem areas, but you’ll also have learned how to use Neo4j efficiently to identify complex relationships in your data.

Creating a geometry layer in Neo4j with neo4j-spatial

neo4j-spatial is an extension of Neo4j containing tools to represent and manipulate complex spatial data types. In this section, we are going to learn about this plugin by importing data on districts in Manhattan and finding points of interest located within each district.

Introducing the neo4j-spatial library

The neo4j-spatial plugin can be installed by downloading the latest release jar from https://github.com/neo4j-contrib/spatial/releases and copying this jar to the plugins directory of your active graph. You then need to restart the graph for the changes to be taken into account. Once this is done, you can check that the spatial plugin is enabled by calling the spatial.procedures() procedure, listing all available procedures within the plugin:

CALL spatial.procedures()

With this plugin, we will be able to do the following:

  • Import from well-known geographic data formats such as shapefile
  • Use topology operations such as contains...
