Since this is part of my “Brief Intro to Epi” series, I cannot cover all these types of charts in detail. I will cover the more popular ones in slightly greater detail, and just mention the others in passing.

So, in passing...

Group Bar Charts are used to illustrate data from 2-variable and 3-variable tables, especially when an outcome variable has only 2 categories.

Stacked Bar Charts are difficult to interpret.

Deviation Bar Charts exist, but are not commonly used.
