Another ridiculous pie chart (achive here) — this time in duplicate!

1) Pie charts are among the worst methods for transmitting numerical information. Bar charts are much better.

2) You have the data for each year for the last 10 years. Show it! The more data that you show people, the more informed they will become.

3) Without the numbers for specific categories, it is hard to make sense of things. Has spending on the library/museum increased or decreased (in percentage terms) in the last decade? Looking at the pie chart, we can’t tell!

If I were a Trustee, I would be quite critical of this chart. Doing it right takes no more time than doing it wrong.
