I have a computational quality to my mind, I suppose. When I was a kid, I was obsessed with video games. I reprogrammed games, and this eventually landed me a column in a magazine. That's how I got into print journalism: writing about video games.

Visualizing information is a form of knowledge compression.

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.

Some of the commercial work I do is helping people to improve their presentations and add some design thinking. There are so many amazing things in science, and such great data, which can often be locked away. It's in the minds of these amazing practitioners, who can't necessarily express what they want in a visual way.

I remember researching a really complicated article and having trouble keeping track of all the different perspectives. I ended up drawing a diagram to help myself follow how the ideas were interrelated. I looked at the diagram when I had finished and thought, "Oh, maybe I don't need to write the article now - maybe I've done my job as a journalist. I can convey my understanding through the diagram."

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."

I was a freelance journalist, and it was a struggle because I had to pitch all the time, research, and stay on top of subjects.
