For piecharts I think we as sensible scientists 
should print a warning to people that pies are not good to visualise
quantitative information. They are only good to hide information.

I've once wrote a little piechart program
and when I've dug into the literature for visualisation
I found out that piecharts are not a good idea.
Instead of scrapping my program I added the warning.
If people want to hide information, it might be useful. ;>
