How to make a multi-screen interactive

Sometimes you’ll want to join more than one map, chart or other visual together  — but if you’re not a developer it can be a little tricky. This is where the iframe scaffolder by Paris-based developer from Journalism++ Pierre Romera comes in. I made this map — used by Mother Jones — using the tool, which made it simple to … Continue reading

Data journalism in China

Facts are Sacred has just been published in China. This is the new introduction written for this edition. When Western data journalists think about China, it’s often as the subject of data journalism, rather than a source of it. And you don’t have to search hard for smart examples of interesting work: just take Propublica’s … Continue reading

A data journalist at Twitter

In 2013, as I was about to start at Twitter, Alex Howard wrote a piece pondering on just what a data journalist would do at a tech company. Now, as I’m about to begin a new adventure, I thought I should collect together a selection of the projects worked on with some amazing developers and others … Continue reading

Gallery: Space, the universe and everything visualized

Last year the first two of three infographics books for children that I have worked on were published. Now you can get the third. Space is designed by the brilliant Jennifer Daniel and the images above are a selection of some of the spreads. You can get the book on Amazon right now.

Ebola in charts: data journalism and the outbreak

It’s a crisis unparalleled in modern times: the biggest outbreak of Ebola ever recorded. So, what do we know about it? Data journalism is about taking the key data, breaking it down and making it accessible. So a major story like this is where getting the data can help us understand it better. So what data … Continue reading

What data journalism told us about #Ferguson

Data journalism in 2014 has taken a shift towards instant reporting: today it is about applying analysis and discovering data around events in the news as soon as they happen. It’s been a week since the police shooting of unarmed Michael Brown in Ferguson, Missouri, what have we learned from data journalists about the events and issues behind … Continue reading

Twitter Reverb: how we made a new #dataviz tool

Anybody who tells you that working with big data is straightforward is probably lying. Often, what you’re trying to do is to filter it down, make it simpler and easier to deal with. Twitter data is no exception—there are more than 500 million tweets sent every day and if you’re “non-eng” (not an engineer), that is … Continue reading

Data journalism needs to go mobile

Why? Well, it depends if you actually want anyone to see it. It’s been happening for a while but really matters today as smart phones become ever more ubiquitous  — now over 65% of the US market — and more and more people now access the web with their phones. But what does that mean … Continue reading

Gallery: taking #dataviz beyond infinity

If you were in downtown San Francisco recently, you may have seen a blue box in the middle of the street (yes, it was Tardis blue), next to the Embarcadero centre. Inside was a data visualisation conceived and created by Roundhouse in collaboration with Universal Everything. “Data visualisation” is underselling it. I got to work on the data part of … Continue reading

How to make an animated map with CartoDB and Torque

If you want to make an animated map (and you’re not a coder), there are not  a lot of options out there. CartoDB is the best. You can use it to make rather gorgeous choropleths but it excels at mapping large numbers of points. That makes it perfect for mapping Tweets — and I used … Continue reading
