Tableau - Tree Map


Advertisements

The tree map displays data in nested rectangles. The dimensions define the structure of the tree map and measures define the size or color of the individual rectangle. The rectangles are easy to visualize as both the size and shade of the color of the rectangle reflect the value of the measure.

A Tree Map is created using one or more dimension with one or two measures.
