Example 300: Simple Pie Chart

1//! V7's Pie Chart control has been improved again.  Size this control and use the vertical scrollbar to
2//! quickly see multiple variations.  Note we've added a zero data point for the first subset.  This demonstrates
3//! how ProEssentials automatically annotates zero slices and controls which slices are included in the "*Other"
4//! slice grouping.  Sizing to a small square stresses our text positioning logic that demonstrates three
5//! algorithms attempting to prevent text from overlapping.  There's no other pie chart on the market that
6//! offers this attention to image detail.

8//! Double click slice label to explode. //
9//! Use vertical scrollbar to revolve through subsets. //
