Also known as a Bee Swarm Box Plot, Swarm Plot. Not to be confused with a Jitter Plot.

A Beeswarm Plot is a type of visualisation that displays individual data points in a way that they don’t overlap, resulting in a plot that resembles a swarm of bees. The main aim of a Beeswarm Plot is to display the distribution and density of data along a numerical axis more clearly.

In this visualisation, data points are arranged compactly along a single axis, ensuring they do not overlap. Rather than random jittering (like on a Jitter Plot), points are shifted minimally to avoid overlapping. This method ensures all data points remain visible, enhancing the visibility of density and variation. Additionally, colour can be used to represent different categories or an additional variable.
