Ice Column Chart

INTRODUCTION
English translation pending.
CORE DEFINITION
The icicle chart, or icicle plot, is a hierarchical visualization that arranges tree-structured data in top-down bands, where the width of each node encodes its share of the total and depth shows the level in the hierarchy. The core proposition is that structure and proportion are read in the same view, which makes imbalances between branches immediately visible. The key qualification is that very deep hierarchies produce slivers too narrow to read, so the number of levels must be limited deliberately.
SCAFFOLDING EFFECT
Reduce cognitive load
- Proportion at a glance: Read the size of every branch in one view instead of comparing separate tables. - Imbalance hunt: Look for branches whose share looks wrong relative to their importance. - Depth control: Limit the number of levels shown so narrow slivers remain readable.
Anchor fast decisions
Rectangle width encodes the quantity of each node and vertical position encodes its depth, so a single glance delivers both the structure of the hierarchy and the relative size of every branch. Because the two encodings are independent, a viewer can spot a branch that is structurally deep but proportionally tiny, which separate tables and pure tree diagrams hide.
