There are two mentions of pie charts in the course - these are offensive to data enthusiasts everywhere! #130

The second link does make it clear that this is a poor choice of figure and is misleading.

The first makes a mention of https://clauswilke.com/dataviz/visualizing-proportions.html#tab:pros-cons-pie-bar

I'd like to change the language to be more firm on the evil of the pie chart, and perhaps add https://www.data-to-viz.com/caveat/pie.html as an additional external link.

Wanted to make this an issue rather than just change to invite a discussion on the off chance someone feels strongly about pie charts having a place in data science.
