I started moving into online work, and that exposed me to design and the impact it has on the flow, shape, and narrative of the story. This got me thinking that maybe this is a way of doing journalism, a way of telling stories and revealing patterns.

By visualizing information, we turn it into a landscape that you can explore with your eyes, a sort of information map. And when you’re lost in information, an information map is kind of useful.

It's enjoyable to just drink in an image. It's effortless. That struck me as an interesting way of looking at it: I do all the grunt work so you can enjoy.

I've been working on a graphic about carbon emissions. It's an incredibly simple graphic - a bunch of blocks and a table below it - but it's taken me three weeks to design. For some reason it just wasn't working. Then finally I realized there was a number present, which I was rendering in each version, that wasn't necessary for the understanding of the piece. This figure was getting in the way and distracting from the main flow of the narrative. As soon as I pulled that graphic out of the design, it sprang into focus. Suddenly it worked.

What I tend to do is blend quantitative with the qualitative to allow me to plot the qualitative data in some way. It's a question of what quantitative data are most applicable. So I'm playing with that, merging the two.

There's a tendency in graphics to allow the trimming of certain parts. But I think that if you're open about your process, your methodology, such as introducing thresholds, introducing filters, techniques people use in research and data management, it's legitimate. It's legitimate to say, "We're only going to show data above this level, or between levels."

Design has a powerful impact on the viewer. It has authority, and data also has the same air of authenticity and detail. It can be hard to argue with a graph, and it's hard to argue with data. So to combine data with a strong visual impact creates a powerful message.
