All-app template, with interactive and animated 2D pyramid and funnel charts. Unlike the usual linear Pyramids, in which each segment's height is proportional with item's value, Surface Pyramids have each segment's surface area proportional with the item value. Slice them up, or collapse the slices back, with single clicks. Show data labels, inside or outside, as values or percent. Show legend with series names. Each slice is a total of values for a single series, a country name in this case.
