The examples shown are why pie charts are often not a good idea when categories are massively different in size. There are often better alternatives.

I've long wanted to use a pie chart but with lines to denote which slice is which, but the library used for the charts do not support this. A different chart is probably the way to go here. As to what chart that is, that's a ? for now.

For the data illustrated in the examples, a bar chart would probably be best.

The example "pie chart" in https://www.mediawiki.org/wiki/Extension:Chart isn't very pie-like:

What did you do to it?

@Bugreporter2 I did nothing. Not sure how this is my problem? This is a task for a Toolforge tool; it'd be great if you checked the task's projects beforehand.

Offtopic, but I've fixed the chart: https://commons.wikimedia.org/w/index.php?title=Data:Example.Pie.chart&diff=prev&oldid=1264919181
