Treemap
Nested rectangles sized by value that show a whole and its parts.
The idea
A treemap fills a rectangle with smaller rectangles whose area is the value, grouped by parent. It is the compact way to show a big hierarchy with hundreds of items that a bar chart could not fit. Colour can carry a second measure.
Where to use it
- Budgets split into departments and line items
- Sales by region, country and product
- Portfolio and market-map breakdowns
- Any category tree with sizes attached
