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.
David MccandlessI 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.
David MccandlessI'm doing a lot of cognitive processing. I'm gathering research. I'm processing it. I'm arranging the data. I'm sorting out the narrative. I'm designing. It's almost as if I do all the cognitive work that you then don't have to do. I digest it, process it, and then offer something that's very easy for you to digest.
David MccandlessI'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.
David MccandlessFor years I thought I was just a writer, but when I sat down to design and started playing around with it, I realized that, really, it's pretty easy. Obviously it's more than just a set of rules, but the basics of design are actually pretty simple and quite mathematical. The link between data and design works at quite a fundamental level.
David MccandlessThe classic one for me is one of my favorite images - left-versus-right political-spectrum image. I was trying to visualize the concepts on the political spectrum. I'm left-leaning, and I discovered as I was doing it that I had an impulse to make the left-hand side appear better than the right-hand side. That was manifesting in the way I was choosing certain words, framing certain ideas. I shared it with a few people, and they all said, "Oh my God, this is really biased." I hadn't seen it at all.
