Neo4j is designed to be very visual in nature. Using nodes and relationships, users can easily model their data into something developers, analysts, and leaders alike can understand. The Cypher query language is also structured visually with ASCII-art to make query-building and maintenance easy to read and adapt.
Graph visualization takes these capabilities one step further by drawing the graph in various formats so users can interact with the data in a more user-friendly way. With visualization tools, a full or partial graph can come to life and allow the user to explore it, setting various rules or views in order to analyze it from different perspectives.
The pages in this section are designed to help you understand how to export your graph data in Neo4j for display as a visualization using a variety of tools provided from open source, Neo4j, or partners. Each tool provides certain capabilities, so you can choose which one suits your needs best. We will also show how to use the tools to display your data in Neo4j.
There are a variety of ways to view data in Neo4j without the pictorial representation. You can return results as json, xml, tabular formats. So why would someone choose to represent the data visually?
A unique capability of graph data is that it is very easily shown in a visual format. A graph visualization provides additional value for data analysts and business users, as well as developers. Anyone reviewing the graph can see the connections, determine areas of interest, or quickly assess the current state and organization of the data. As you can imagine, this can provide insight where other types of data formats cannot, bringing enormous value. Visualizations help make anomalies or relevant patterns stand out to help human eyes and brains detect them, where other types of data formats might not highlight hidden structures as well.
Let us look at a very rudimentary example of this using our movie data from the earlier data modeling section guides.
In the graph view below, we can easily pick out that
Lana Wachowski directed both
Cloud Atlas and
The Matrix movies, where in the tabular representation, that information is not as clear or easy-to-find.
Even if you feel that the relationship is not hard to find in the tabular format, imagine if we were looking at a graph that contained these individuals' entire filmography careers, as well as hundreds of other actors, directors, and film crew members. The connections could easily be lost in a non-visual presentation.
Neo4j has two main visualization tools that are built and designed to work specifically with data in Neo4j’s graph database: Neo4j Browser and Neo4j Bloom. We will briefly discuss the key details of each here.
Neo4j Browser, a developer-focused tool that allows developers to execute Cypher queries and visualize the results, is the default developer interface for both Enterprise and Community editions of Neo4j database. It comes out-of-the-box with all of Neo4j’s graph database offerings, including Neo4j Server (community and enterprise editions) and Neo4j Desktop (all OS versions).
Its visualization functionality is designed to display a node-graph representation of the underlying data stored in the database in response to a given Cypher query, showing circles for nodes and lines for relationships. Neo4j Browser also provides some functionality for styling with color and size based on node labels and relationship types, or you can customize your own styles by importing a GRASS (graph-stylesheet) file for Neo4j Browser to reference. You can also use the built-in drop-down buttons on query result panes to easily export the data to PNG, SVG, or CSV formats.
Bloom is Neo4j’s standalone product for visualization that is accessible with a commercial license or for free with Neo4j Desktop (single user). This tool was designed for business analysts and other non-developers to interact with data stored in the graph database without writing any code.
Users can use natural language to query the database and explore patterns, clusters, and traversals in their graph data. It is also possible to create different dissections of the graph (called perspectives) that allow users to view different aspects and slices of graph data for further analysis.
Outside of Neo4j’s offerings, partners and community members have built tools and integrations to connect graph data in Neo4j with more graph visualizations. Learn more about options and functionality of these tools in the guide linked below.
Perhaps you are not looking for standard graph (node and relationship) visualizations, but want to look at graph data in other ways. Organizing the data as charts, heatmaps, 3D, and more is also possible with Neo4j. Find out what is available and where to find them on the next guide.
