Growth rate? Growth of what? Rate over what amount time? Heck, you don't even get the numbers. There's no time, date, footnote, asterisk. All the viewer ends up with is a question mark. It's happening over and over again, like this one I blogged about a few months ago.
Data Ink Ratio = (data-ink)/(total ink in the plot)
This is minimalism at work in infographics. Data stands on its own. It does not need fancy images and gussied up fancy texture backgrounds.
Here's a case study from Tufte's work that I find fascinating. Chart junk of the worst order (not even qualifying for porn -- it's not pretty):
Yet when you apply a high data-ink ratio and a whole lot of ingenuity (designers thrive on constraints), what you can get can be dramatically better:
Look at that! Cut the crap and let the data speak for itself -- and the mundane / unintelligible suddenly takes on meaning and life.
The problem with chart porn is that it gets in the way of the message you're communicating. I'm a big believer in minimalism, and these charts are anti-minimalist. They are filled with lines and fury signifying nothing. (rather like life, some would say)
Oh, Mint. Please use your data for good, not for more chart porn.
