I want to create an animated pie chart in JavaScript. I have done some R&D myself and found the Google Charts API.
But my major concern is the actual data is sent to the Google server for creating the charts. I am concerned about sending my data to a third party.
If you're concerned about sharing data with a third party, you might consider an offline charting library, like ZingChart. It gives you the ability to create animated pie charts quickly and easily without the need to transfer any of your data to a third party. This charting library works offline, and is dependency free. There are a number of animations that can be applied to the various types of charts, including pie charts. Check out this animated pie chart demo.
Lists of the different animation effects, methods, and sequences can be found on the animation docs page.
I'm a member of the ZingChart team, so please feel free to ask if you have any questions! :)
I suggest you use jPlot! You can do Pie and Donut Charts, Bar Charts, Line Charts and much more!. See the API here.
