introduction

A treemap is a visualization that displays hierarchically organized data as a set of nested rectangles, parent elements being tiled with their child elements. The sizes and colors of rectangles are proportional to the values of the data points they represent.

1 or more dimensions, 1 measure, such as: dimension [province] measure [profit] We get a rectangular tree plots representing profit sizes for different provinces. 0 dimensions, multiple measures, such as: dimension [empty] measures [profit] [sales] We get a rectangular tree representing the relationship between profit and sales.
