A Treemap Chart provides a hierarchical view of your data and makes them easy to compare. Usually, the small rectangles are logically grouped into some further categorical family and are coloured to indicate a key attribute of the data. Create flowchart, UML, ERD, DFD, ArchiMate, BPMN. Create a chart using data or drag and drop to interactively modify data directly from the chart. Online treemap maker with fully customizable treemap templates. The size of these sub-category rectangles represents a quantitative value. Designer-crafted, eye-catching treemap templates. The arrangement is typically (but not always) a rectangular area divided up into smaller rectangles to represent sub-categories. The Treemap visualization is used to display hierarchical data as a set of nested rectangles. Also, we will learn to create Treemap in Qlik Sense. A treemap is used to show the composition of a whole when there are many components. Moreover, we will look at the use of Treemap Qlik Sense Visualization.
