What is a Caterpillar Diagram?

A Caterpillar Diagram is a visualization technique used for analyzing univariate time-series data. It consists of a series of colored circles with varying radii. The circle's color represents the direction of change in the time-series data, and the circle's size shows its variation.

It implements the innovative and intuitive Difference of Differences (DoD) approach to create a color schema. As proposed, it segregates the time-series data under analysis into a cohort of three consecutive time units. Further, it utilizes the unsigned differences between observations to assign a size to each cohort. This novel visualization technique can segregate the time-series data using seven colors or five stages of Aggressive, Ascent, Descent, Controlled, and Status Quo.

Further, the proposed mechanism utilizes the accumulated color information regarding each cohort to forecast the next step transition using a stationary matrix of Markov Chains.
