Visualize graphs with G.V()

This page describes how to use G.V(), a third-party desktop application that integrates with Kuzu to provide a rich set of visualization and analysis features for your graph data.

When is it beneficial to use G.V()?

G.V() provides a wealth of tools to support developers and data analysts working with graph databases. At it’s core, It is an integrated development environment with which you can write and execute Kuzu Cypher queries, and analyze the results interactively. It’s also built for large scale, high performance graph visualization to analyze trends in your graph data.

Key features

G.V()’s Kuzu Cypher query editor offers a powerful suite of features to accelerate and enhance you query writing experience, by offering essential development features:

• Cypher syntax validation
• Autocomplete suggestions based on your graph data schema
• Embedded schema documentation so you can immediately identify the relevant labels and property keys for your nodes & edges
• Procedure autocomplete
• Query parameter support

Installation

G.V() is a desktop application that can be installed on Windows, macOS and Linux. You can download the installer from their home page. It is also available for deployment as a web application on AWS Marketplace, or self-service deployment via Docker. To get started with self-service deployments, please contact support@gdotv.com.

Connecting to Kuzu

G.V() directly connects to a local Kuzu database. First, open the G.V() application and click on the “New Database Connection” button. You can select Kuzu from the list of supported databases as shown below.

The next step is to specify the path to the Kuzu database you want to connect to. Make sure that you type in the absolute path to the database. By default, G.V() will try to connect to the Kuzu database in read-write mode. If you want it to connect in read-only mode, you can select the “Read Only” button shown. Once selected, you can click on “Test Connection” to make sure that the connection is successful.

Query using Cypher

You’re now ready to write and execute Cypher queries in G.V()! The default query is loaded in the query editor, which can be executed by clicking on the “Play” button or pressing Ctrl+Enter (or Cmd+Enter on macOS). You should see your graph data visualized in the main panel.

The default visualization is a graph of the results, if you choose to RETURN * or return nodes, relationships, or paths from your query. You can also choose to visualize the results as a table by returning the properties of the nodes or relationships.

No-code Kuzu Exploration

G.V()’s Graph Data Explorer gives you the ability to quickly query your Kuzu instance without the need to write a Cypher query, through the use of easily configured filters. Combined with their graph exploration features, you can explore your Kuzu data in just a few clicks, with no prior knowledge of Cypher!

View graph schema

You can view the graph schema by clicking on the “View Graph Data Model” button in the left sidebar. This displays the graph schema in a convenient layout that shows the node labels, relationship labels and their associated properties (and their data types).

Advanced features

In addition to basic Cypher query editing, G.V() offers a richer set of features to help you explore, debug and analyze your graph data. Below are some of the key features:

Query history

Access your previous queries and quickly re-run them.

Save queries

Save your queries for future use, and organize them into folders. Queries can be configured with Cypher parameters (e.g. MATCH (s) RETURN s LIMIT $limit) which G.V() automatically detects and prompts you back for, meaning you can effectively create and categorize parameterized reports against your Kuzu instance.

Advanced Graph Visualization Customization

G.V() offers a comprehensive set of features to customize the look and feel of your graph visualizations, giving you the ability to create insightful renderings of your graph data for analysis and demonstration purposes.

View query profile and explain query

You can also view Kuzu’s internal query execution profile and get a detailed explanation of the query plan and execution strategy.

Custom graph layouts

Choose from a variety of graph layouts to visualize your data

• Force-directed layout (default)
• Circular
• Grid
• Community layout
• Tree layout (vertical and horizontal)

There are many more features to explore than what we’ve listed here! Please see the release announcement post that details all the important features along with examples.
