A guide to graph visualization

Here you’ll discover everything you need to know about graph visualization, with links to articles by experts, white papers, tutorials and more.

What is graph visualization?

a visualization of a mafia network

Graph visualization, also called link analysis or network visualization, is a way to visually represent connections between entities in data.

The most effective way to visualize graphs is through a node-link model, where nodes represent entities and links represent connections.

These nodes and links can be anything – transactions between accounts, devices on a network, or phone calls between friends.

It doesn’t matter how large or small your data is, what it contains or where it’s stored. As long as there are connections you need to understand, you’ll find value in visualizing graphs

Why visualize graphs?

The world is densely connected. Often, to answer important questions, you need to understand those connections.

That’s where graph visualization can help. There are four key reasons behind its popularity:

  • Intuitive – The node-link graph model makes sense instantly, even to people who’ve never worked with graphs before.
  • Fast – Humans are great at spotting patterns when data is presented in a tangible format. Identifying trends and outliers is quick with graph visualization.
  • Scalable – graph visualization lets analysts see beyond individual data points, revealing context, structure and individual connections.
  • Insightful – truly interactive visualizations let analysts engage and explore connected data, unlocking previously buried insights.

Getting started

For end-users, graph visualization is an intuitive and liberating experience. Going beyond tabular and aggregated views unlocks all kinds of analysis opportunities that would otherwise be impossible.

But the teams responsible for creating graph visualization tools often face a steep learning curve.

There are fundamental concepts to understand, and best practices to follow to make sure your application is as effective and insightful as possible. We’ve summarized them into a three-part, non-technical, introduction to the world of graphs.

Part 1: the basics of graphs

Understand the node-link graph model, and whether it’s the right approach for your data visualization project. The node-link graph model

Part 2: design best practices

When you’re planning a graph visualization approach, you’ll need to consider how your users will interact with their data. Designing your best app
