Interactive graphics for data analysis

I got a copy of Martin Theus and Simon Urbanek’s Interactive Graphics for Data Analysis a couple of years ago, whence it’s been sat on my bookshelf. Since I’ve recently become a self-proclaimed expert on interactive graphics I thought it was about time I read the thing. Which is exactly what I did last weekend

Nomograms everywhere!

At useR!, Jonty Rougier talked about nomograms, a once popular visualisation that has fallen by the wayside with the rise of computers. I’d seen a few before, but hadn’t understood how they worked or why you’d want to use them. Anyway, since that talk I’ve been digging around in biology books from the 60s and

Legendary Plots

I was recently pointed in the direction of a thermal comfort model by the engineering company Arup (p27–28 of this pdf). Figure 3 at the top of p28 caught my attention. It’s mostly a nice graph; there’s not too much junk in it. One thing that struck me was that there is an awful lot

Presenting Immer’s barley data

Last time I talked about adapting graphs for presentations.  This time I’m putting some of the concepts I discussed there into action, with a presentation of Immer’s barley dataset.  This is a classic dataset, originally published in 1934; in 1993 Bill Cleveland mentioned it in his book Visualising Data on account of how it may

Adapting graphs for presentations

I’ve just finished reading slide:ology by Nancy Duarte. It contains lots of advice about how to convey meaning through aesthetics. The book has a general/business presentation focus, but it got me wondering about how to apply the ideas in a scientific context.  Since graphs from a big part of most scientific talks, and since that’s
