Tag: pie-chart

What do we see when we look at slices of a pie chart? Angles? Areas? Arc length? The answer to this question isn’t clear and thus “experts” recommend avoiding pie charts at all.

I went through my Machine Learning tag feed. Suddenly, I stumbled upon a pie chart that looked so terrible, I was sure the post would be about bad practices in data visualization. I was wrong. The chart was there to convey some information. The problem is that it is bad in so many ways. It is very hard to appreciate the information in a post that shows charts like that. Especially when the post talks about data science that relies so much on data visualization.
