Icicle: JavaScript Data Grid Demo

A hierarchy as nested bars, each band as wide as the share of the total beneath it

type: 'icicle', y

This draws a hierarchy as nested bars, each band as wide as the share of the total beneath it. It shows how a total breaks down through levels, so where the weight sits in a tree reads as width.
