Beauty is not a substitute for meaning

“Allowing artist-illustrators to control the design and content of statistical graphics is almost like allowing typographers to control the content, style and editing of prose.”

– Edward Tufte

I’ve been re-reading Tufte recently, and this comment jumped out at me. Although the subject is data visualisation, the same is true¬†for any kind of visualisation. If you’re going to create a meaningful¬†representation of concepts, then you have to understand what those concepts mean. And if you’re going to understand what they mean, then you’re going to need either a lot of prior knowledge or the ability to ask a lot of really good questions.

Beauty is important, but if your intention is to communicate then it is not a worthy substitute for meaning.
