INTRODUCTION

CORE DEFINITION

An alluvial diagram visualizes how categorical data flows between different time points or states, rendering movement like river deposits. It makes flows visible: where customers come from, where they go, and where they drop away along the way. Band width encodes the volume of each transition, so the dynamics of a whole population can be read at a glance.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Map the movement: lay out category distributions at each time point and connect them - Read the width: treat each band's thickness as the volume of flow it carries - Find the leaks: look for where flows converge, diverge, or disappear entirely

anchor

Anchor fast decisions

Each category is a column and each transition a band whose width is proportional to the volume moved, so the diagram encodes flow with area and change with connection. Convergence and divergence become visible shapes instead of numbers, which exposes where value accumulates and where it leaks out of the system.
