Data visualization library

Data visualization is an incredibly useful storytelling tool. By using graphics and visuals to bring your data to life you can make your content so much more digestible and actionable that just be presenting a lot of numbers.

Data vis is both a science and an art – how do you tell an accurate story and make it all somehow come across as relevant to your viewer? How do you draw them in whilst staying true to the facts you’ve gathered?

We think one of the best ways to learn is to practice, and that’s what we do. Every month we do a piece of true data visualization for our monthly newsletter (you can subscribe to that here), and so here is our library of data vis examples for you to browse through. We’ve also provided the prompts if you want to have a go yourself.

When does coffee reach Perfect Drinking Temperature?
