Treemaps display hierarchical 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. A leaf node’s

rectangle has an area proportional to a specified dimension of the data. It is an alternative way of visualizing the structure of a tree diagram. Treemap can be easily done using the Treemap library.

Once you control this technique, you can transform your static treemaps in **interactive treemaps** using the d3TreeR library. See several examples below
