How do I make a pie-in-pie chart with MSChart?

I've downloaded MS Chart samples and in the gallery it shows a "3DPieInPie.png", which is what I want - but can't see any code to create it!!

enter image description here

Presumably it's ChartType = SeriesChartType.Pie ... but is there another setting that specifies I want the second pie? And how do enter the second set of data? - I've tried adding a new series, but it seems to be ignored.

Check out these answers. They also include some sample code:
