Also known as a Dot Plot, Dot Graph, Dot Chart.

A Cleveland Dot Plot is a simple form of data visualisation that plots dots to compare the values of a one-dimensional variable across multiple categories. On a Cleveland Dot Plot, one axis will list the categories, while the other axis represents a discrete value scale.

A Cleveland Dot Plot serves as an alternative to a Bar Chart and offers a some advantages such as: reduced visual clutter, no need to start from zero, easier value comparison and pattern identification.

These plots are particularly effective for displaying smaller datasets with a moderate number of categories.
