Example 035: Graph showing Demographic Pyramid

1//! This feature represents a new mode of drawing data and axes, a special case
2//! not compatible with mixing plotting styles and full zooming.
3//! Best to set AllowPlotCustomization = False, and
4//! AllowZooming = PEAZ_NONE or PEAZ_HORIZONTAL.
5//! Also note graph annotations take special positioning as demonstrated below.
