Sparklines: Beautiful Evidence or Muddled Graphics?

Do you understand this graphic? It is an example of a sparkline, by Edward Tufte. Tufte was, if not the originator of sparklines, one of its earliest advocates. He wrote about them in his book Beautiful Evidence (2006); he defines sparklines as “small, intense, wordlike graphics, embedded in the context of words and numbers”. Tufte’s ideas were very influential and were taken up by Microsoft in their 2010 release of Excel. But I don't agree with him about sparklines.

Don't Make me Think, original cover


Don’t Make me Think! That title! There are few examples in publishing of a book title catching your attention and at the same time summarising what the book is all about. If books can be reduced to one big idea, then this is the perfect example. Essentially, if you want to build a website, don’t make me think when I use it. Now, fifteen years and a third edition after the book was first published (in 2000), is it still as relevant? Well, Steve Krug helpfully points out the original book’s limitations himself, in the introductory section to the latest edition. Most importantly the book was written before mobile became common. Nonetheless, the basic principle, that a user’s interaction with a website should be based on simplicity, is admirable and of course holds true for hand-held devices as for desktops and laptop PCs.

This is a book that displays its principles admirably. Krug is a great believer in using graphics, cartoons, and diagrams to explain his point. The book is very short (I read it in under three hours, and the original edition must have been even shorter).
