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.

Can data journalism be taught?

Can you really teach data journalism? It’s a dumb question that I’m soon going to find the answer for: from next week I start teaching at Berkeley J-School (you can see my syllabus here). There’s no shortage of advice on teaching journalism students. If you believe what you read, young reporters need to learn to code; not … Continue reading

The five Ws of data journalism

This is taken from materials for an introduction to data journalism, a MOOC course run earlier this year. You can read more about the course here.  1) Who? Where did the data come from? Why does this matter? This could be the most important W. Because data, like any kind of information, can be wrong … Continue reading

Journalist datastores: where can you find them? A list.

Where do journalists post their data? It’s a pretty core tenet of open journalism that you share your sources; i.e. , you write a story about data then you make numbers available to download. It matters because: Your audience is more likely to trust your story if they can test the sources Someone out there probably … Continue reading

Ebola in charts: data journalism and the outbreak

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

If devolution killed national data, what would Scottish independence do?

The quality of government data is quite possible the last thing on most voters’ minds when Scotland decides whether to leave the UK this Thursday. But, believe it or not, it matters. I wrote this piece back at the Guardian on devolution and open government data. An independent Scotland would probably be the ned of … 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

Saving the oceans: with data

Do you know how big the giant ‘garbage patch’ floating in the Pacific is? The floating ocean of trash and sludge may be a phenomenon of our treatment of the oceans but nobody really knows how big it is — with estimates ranging from 270,000 square miles to 5.8 million. Or even”the size of Texas“. The … Continue reading
