The Latest Shameful Pie Chart

The latest in what is threatening to become a series of insidious examples of pie charts in a real special pie chart. This one was spotted by Mr R Lambert of Winchester. Even if you were a fan of pie charts you would have to admit that there are massive problems here. For starters, those […]

The Pie Chart So Bad I Had to Censor It

You will probably be well aware by now that I think that pie charts are the worst way to display your data. As well as that article, I have occasionally found the need to talk about how much I dislike pie charts – and this is just such an occasion. Today, I have an example […]
