Install TAChart (it's under components folder), it already has pie
chart.

I tried to install TAChart and failed... Meanwhile, I have realized
that TAChart is part of the default Lazarus installation package.
tChart is part of the Lazarus components and to get a pie chart, you
simply need to add a PieSeries in tChart.

But there's no really good documentation of TAchart, and the demo
program (folder lazarus/components/tachart) generates several compiler
errors... I seems that the demo program has not been updated since
TAchart has been changed.

Try using daily snapshots, TAChart is one of many components that get
quite a lot of improvements.

Note that for a long time (at least since Lazarus 0.9.28) there are
many demo
programs in "components/tachart/demo" subfolder,
instead of the single demo you are talking about.
Please make sure you are using recent enough Lazarus version.
