Pie Chart in Google Charts
Pie Chart
A pie chart is a circular statistical graphic, which is divided into slices to illustrate numerical proportions. In a pie chart, the arc length of each slice is proportional to the quantity it represents. In other words, it uses pie slices to show relative sizes of data. A pie chart is rendered within the browser using SVG or VML. It displays tooltips when hovering over slices.
