✗ Patterns: The bars also have patterns, which, although very pretty, distract the eye from what matters (namely the data). These are completely unnecessary. ✗ Cylindrical bars: Were my data so sewage-like that I wanted to put them in silos? The cylinder effect muddies the data and distracts the eye from what is important. ✗ Badly labeled y-axis: ‘Number’ of what? Delusions? Fish? Cabbage-eating sea lizards from the eighth dimension? Idiots who don’t know how to draw graphs?
