Also known as a Strip Plot.

A Counts Plot is a variation of the Strip Plot / Dot Distribution Plot that plots circles of varying area size to help provide a better view of any overlapping data points. Like on a Dot Distribution Plot, the function of a Counts Plot is to visualise the data distribution across multiple categories for comparison.

Each circle on a Counts Plot can represent a single data point or a count with the area size being proportional to the count or number (or the aggregate of values) of data points that would overlap at that position on the axis. Alternatively, the area size of the circles could also be used to visualise an additional variable not present on any of the axes.

A Counts Plot can be displayed either horizontally or vertically. Typically, the circles are a single colour, but colour coding can be used to distinguish categories apart or visualise an additional variable. Also, to help make overlapping circles more visible, the opacity can be reduced.

Another variation of a Count Plot is essentially a Cleveland Dot Plot but with the size of the dots varying in proportion to the count or variable. This could be used to compare single or multiple data series or subcategories (of around 2-4) to each other.
