Visualizing graphs is hard. When I started working with graph data, I realized it takes significant work to create intuitive graph visualizations. Thankfully, a ton of tools have been developed that make graph visualization a cakewalk.
In this article, I’m zooming in on some of my favorite tools. I group these tools into categories based on their functionality and purpose. After reading, you should have an overview of the graph visualization landscape, and (hopefully) find a tool that fits your visualization needs.
Categories of Graph Visualization Tools
Before we dig into the tools, it’s important to be aware of the categories of tools out there. All visualization toolkits were built with a specific purpose in mind, so you’ll have to make sure the tool’s purpose matches your need.
I group all graph visualization tools into four main categories:
- Development tools, to help developers work with graphs.
- Exploration tools, to help analysts explore data relationships.
- Analysis tools, for revealing trends & discrepancies.
- Reporting tools, to create and organize data reports.
In the image below, I organized some of the most popular graph visualization tools by their main category. On the vertical axis, I’ve plotted the product type (a Neo4j product, community project, or enterprise software).
Note that some tools sit in between two categories, in this case, the tool can be used for both purposes. Now that we have a high-level overview, let’s dive into some of the best graph visualization tools.
1. Neo4j Browser (Development Tool)
The Neo4j Browser is likely the first thing you’ll run into when working with Neo4j. A tool for database developers to run Cypher queries, the Browser lets you render query results in a graph or table format. Although limited in visualization capabilities, I use it daily to rapidly design and optimize Cypher queries.
- Easy to get started, but limited visualizations and styling choices.
- Direct views of your graph data, but requires (technical) Cypher knowledge.
- Great for rapid query development, but no saving/embedding/sharing of visualizations.
2. Neo4j Bloom (Exploration & Analysis Tool)
Neo4j Bloom is a tool for interactively exploring Neo4j graphs. Whereas the Neo4j browser is mainly used by developers, Bloom is suited better for data analysts — those who want to dynamically visualize big graphs. Bloom supports text-based search, allowing people with little Cypher knowledge to investigate a Neo4j graph.
- ‘Point-and-click’ graph exploration.
- Performant views of large graphs with custom styling.
- Edit your Neo4j graph with a visual interface.
- Storing and sharing graph perspectives.
- Rendering different graph layouts.
3. Neovis.js (Development Tool)
- Connect directly to the Neo4j instance to get live data.
- User-specified style properties based on label, property or community.
- Configure hover/click functionality for nodes.
4. Popoto.js (Development Tool)
popoto.js is another community-driven JS library for creating embeddable visualizations. popoto.js is based on the widely used D3.js library, supporting a large number of visualizations. It also contains an interactive and customizable visual query builder for Neo4j. There are a great number of examples available online on how to use popoto, as well as how to extend it with custom styling.
- An interactive visual Cypher query builder with a direct Neo4j connection.
- Embeddable into webpages, with a variety of examples available.
- Powered by the widely used D3.js visualization library.
- Custom styling by extension.
5. KeyLines (Development Tool)
- Support for Time-based analysis, geospatial graph analysis, social network analysis.
- Support for geographical (map) visualizations.
- Custom graph layouts (grouping) & styling.
- High-performance WebGL rendering.
6. CytoScape (Development Tool)
CytoScape is a tool originally built for visualizing biological networks, but it has recently seen uses in a variety of network analysis use-cases. The tool comes in two flavors:
- CytoScape Desktop (A standalone Java-based visualization tool)
CytoScape.js is by far the most extensive open-source library available for visualizing graphs — supporting graph layouts, advanced styling, event handling and much more.
Even though Neo4j support is not a core feature of CytoScape Desktop, several plugins exist to build visualizations directly from your Neo4j database.
- Highly optimized graph rendering.
- Uses layouts for automatically or manually positioning nodes.
- Custom styling.
- Easily embeddable into web applications.
- Open source, easy to extend with custom functionality.
7. yWorks Neo4j Explorer (Exploration Tool)
The yWorks Neo4j Explorer is a free, web-based tool for exploring a Neo4j database. The tool wasbuilt by yWorks, the company behind the widely used yFiles JS library, to demonstrate the capabilities of the yWorks framework for graph data. It consists of two main components:
- A ‘Schema view’, to see the structure of the node labels and relationship types in your Neo4j database.
- An ‘Explorer view’ for searching and navigating through your graph.
The yWorks explorer is a great option for those looking to get started with graph exploration with a simple and intuitive interface, but has limited options in comparison to (paid) enterprise products.
- Visualize and explore the Neo4j database schema.
- Modify the database schema — hide and show parts of your model.
- View a Neo4j schema in different layouts (organic, hierarchical, radial).
- Basic Graph-based search for node/relationship properties.
- Graph exploration based on relationship types & node labels.
- Styling of nodes & relationships with colors, shapes and images.
More details can be found in the blog post here.
8. Linkurious Enterprise (Exploration & Analysis Tool)
Linkurious Enterprise is an on-premises graph exploration and analysis tool. It’s a feature-packed tool intended to be used by data analysts, commonly used for investigation use-cases such as detecting money laundering, cyber threats, and other criminal activities.

I highly recommend checking out the Neo4j blog for more data visualization stories. If you’re working with D3.js, you should check out some of the articles by Jan Zak. Last, I’d like to mention other interesting tools that didn’t make the list:
- ReGraph — A performant graph visualization library for React.
- G6 — another JS library for graph visualizations.
- Graphlytic — a web app for collaborative graph exploration and analysis.

I hope this overview helped you get an idea of the current state of the graph visualization world. There’s a lot of amazing tools out there, and I suggest you give them a try — after all, that’s the best way to see if a tool works for you!
Only when you visualize your graph data, the real power of graphs is revealed: you’ll get insights that you’d never spot before.
