The genius of Hans Rosling, frame by frame

Hans Rosling, a Swedish professor of global health, was known for his TED Talks that revealed him to the public eye. He famously used moving bubbles on a chart to show development trends that surprised his audience. He passed away three years ago, after having inspired people in multiple fields, including data visualization. He is […]

Dataviz Book Review: Show Your Work, by Austin Kleon

Welcome to two of my 2020 resolutions: reading (and finishing) books and writing about the experience. A slow and distracted reader, I often neglect as much as I abandon books. As a perfect example, our first instalment will be Show Your Work, by Austin Kleon (“a writer who draws”). This book probably requires three hours […]

Voilà: 2019 Party in 5 photos

What do you do when a company has moved into new offices, tripled its staff (!) and is turning six years old? You throw a party and you make speeches. We wanted our community to know where we stand now and what we have to offer. But mostly, we wanted to say thank you to […]

What happened when I used an inclusion rider at a data conference

This is the blog post that I wish I would have found when I got invited to speak at a data conference and decided to send them an inclusion rider for women and minorities. I hope this is how you found it. (Also, obviously, I’m virtue signalling and if that bothers you, you can stop […]

But you’ll always find someone on social media to denounce a “dishonest” line chart that enhances the variations by truncating the y-axis. There is usually ample pushback, but it often leads to the question: Where should it […]

Many will understand the underlying phenomenon — a trend, an outlier, a missed target — when they see it in a graph. Humans speak data […]

Eyeo 2018: Conferencing in the age of the Internet

Holding my plate, I spotted a participant eating alone. “Thanks for saving me a seat”, I said as I sat with him.

The upward climb of Max Verstappen in Monaco

It doesn’t matter if you kick a ball, ride a horse, dance with skates or race down a hill: all sports tell the same stories. The underdog. The comeback. The dynasty. The near-miss. The feuds. The rivalry. To get interested in any sport, get to know its stories. One such story is the young prodigy. […]

The convoluted making of a simple chart

Finding the right concept is my favourite part of doing data visualisation. It depends on understanding the topic, the message and the audience and emerges through discussions with the client. Getting to that aha moment where it finally makes sense is a delight. So this is an example of when it happened not once but […]

5 tips for visualizing concepts

What does banking look like, in one image? How about evaluation? And training? That was the easy part. Now, what about the need to improve? Or to speed up and simplify a process? And finally, innovative financing models? Designing information requires to think of visuals for concepts that may or may not have a strong […]
