In information visualization and computing, treemapping is a method for displaying hierarchical data using nested figures, usually rectangles. Treemaps display hierarchical (tree-structured) data as a set of nested rectangles. Each branch of the tree is given a rectangle, which is then tiled with smaller rectangles representing sub-branches.

Sep 29, 2019 · Treemaps are a data-visualization technique for large, hierarchical data sets. They capture two types of information in the data: (1) the value of individual data points; (2) the structure of the hierarchy. Definition: Treemaps are visualizations for hierarchical data.

Sep 6, 2022 · This article explores treemaps. Learn about what a treemap is, scenarios where they might be appropriate, some of the challenges with them, and different ways you can show your data with them.

Oct 16, 2023 · The Treemap, or proportional map (or box map), is a representation in a limited space of hierarchically organized data (although it can also be applied to non-hierarchical data).

Aug 20, 2024 · The Basics of Treemaps; Types of Treemaps; Advantages and Disadvantages; When to Use Treemaps? 10 Steps to Design the Perfect Treemap

What is a Tree Map? The treemap functions as a visualization composed of nested rectangles. These rectangles represent certain categories within a selected dimension and are ordered in a hierarchy, or “tree.” Quantities and patterns can be compared and displayed in a limited chart space. Treemaps represent part to whole relationships.

Feb 3, 2025 · A treemap is a data visualization tool that allows you to view hierarchical data represented as colored rectangles of varying sizes. Treemaps display these rectangles, which represent different categories in a hierarchical structure, in a shape similar to that of a tree.

Treemaps are a special type of chart that display hierarchical data as a set of nested rectangles. The area of each rectangle is proportional to the value represented in the hierarchy. Treemaps are used to visualize different parts of a whole data series.

Mar 17, 2023 · The treemap is a chart type used for visualizing information that displays a hierarchical data set (items are linked to each other). The structure is displayed in nested rectangles that decrease in size, and that make up its different levels.

Treemaps represent an advanced form of data visualization that excels at showing hierarchical data through nested rectangles. While pie charts show simple part-to-whole relationships and bar charts compare categorical values, treemaps uniquely display both hierarchy and proportion in a space-efficient manner.
