Add pie charts

A pie chart is a circular chart divided into sections. Each section is proportional to the quantity it represents. A pie chart contains a single series of data points and is useful for visualizing part-to-whole relationships or data composition. Pie charts can be configured to visualize data as a traditional pie, doughnut, or rose chart. Pie charts are not intended for comparing individual sections with each other or representing exact values (use a serial chart instead). Pie charts are also not meant to show more than seven or eight data points.
