Infographic: Laundry by family member

Data visualisation is difficult to do correctly, but this one just sort of fell out while I was sorting the family’s laundry:

Three stacks of laundry: Mum, Dad, Baby (gigantic)

This sort of graphical representation is easy to do improperly, the most common offence being to scale on more than one axis, causing the area to confusingly increase at a much greater rate than the underlying data:

Three stacks of laundry, badly represented by a scaled picture

Here I demonstrate just one of many ways in which the graph can be manipulated to mislead the eye and thus the viewer.

Edward Tufte would still dislike my original graphic: there’s too much “chart junk” in the background. Move that pillow!
