Marimekko

A Marimekko (100% stacked column with variable width) shows composition within each category. Every column is normalised to 100% height, and column width is proportional to a category total. Both axes read as shares, not absolute values.

When you need absolute heights on the value axis (revenue, counts, etc.) with variable bar widths, use Bar Mekko (barMekko) instead.
