Surface Pyramid Chart
Originally described here: https://forum.highcharts.com/highcharts-usage/surface-pyramid-chart-t39503/
What you have is just a Linear Pyramid: http://jsfiddle.net/cristiscu/sbt6bbfh/6/. Top segment's height is 15% of the full pyramid height.
Surface Pyramid: http://jsfiddle.net/cristiscu/sbt6bbfh/7/. The only change was in the pyramidMode value. Top segment's area was made bigger, to show 15% of the whole pyramid surface.

Thanks for your suggestion! This is probably equivalent to the bubble sizeBy option, which sets whether the bubble’s value should be expressed by its area or its diameter.

A parameter equivalent to sizeBy sounds great! Any news on the progress?
