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.

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

The kids are all bright: infographics for all ages

When my daughter was three and out for a walk on an autumn day, she pointed at a spider’s web and explained what it was. “Daddy, it’s a website,” she said.

#SOTU2014: Visualizing the State of the Union

Just a quick post to highlight this interactive I got to work on with Nicolas Belmonte on the Twitter visual insights team. The idea is that you can use it to navigate around the speech and see the instant reaction on Twitter to each part of it — themed by geography and subject. Pro tip: When … Continue reading
