The Principle of Proportional Ink is a great primer on how to avoid what Carl Bergstrom and Jevin West call "visual bullshit," like this craptacular graph above. The rule is very simple:
When a shaded region is used to represent a numerical value, the area of that shaded region should be directly proportional to the corresponding value. In other words, the amount of ink used to indicate a value should be proportional to the value itself.
They created Calling Bullshit after deciding "the world has become over-saturated with bullshit and we're sick of it." I'm grateful that they stated the truest truth in all of truthdom:
Three dimensional pie charts, such as the one below, are even worse. We cannot think of a situation in which the addition of a third dimension offers anything other than visual bullshit.
Many other examples of visual bullshit in there, so check it out.

Vox made a good video about the history of the Cooper Black typeface, created in 1919 and still in common use today. There’s a typeface that has made a resurgence in the last couple of years. It’s appeared on hip hop album covers, food packaging, and advertising. Perhaps you know it from the Garfield comics, […]
What’s your biggest gripe about power strips? Since most power servers like that are pretty standard these days, your beef probably isn’t about performance or connectivity. No, the biggest rap on trying to use many power strips is the curious engineering decision that often leaves multiple oddly shaped plugs and charging units unable to all […]
Between work, family obligations, and just getting to bed at a decent hour, we all have a lot on our plates these days. So, it’s easy for things like grooming and skincare to never be a high-priority issue. That is until they become a high priority issue. Like when your face constantly breaks out. Or […]
Today’s teachers extol the virtues of hands-on learning, the method of helping students, particularly the youngest children, learn through basic doing. From trial-and-error methods to practice honing their emerging skills, youngsters can soak up a world of learning opportunities when their developing minds are unleashed. While the thought of dropping a smartphone or tablet into […]
