wheel test plugin

Hi,
I have to create a test with 7 questions and each question has a value between 1 and 10.
In the end I have to have a pie chart where the answers are shown. You can see the example on this site: [ redundant link removed ]
do you know a plugin or online service that can do it?
Thank you for your support.
