Main idea. 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. A leaf node’s rectangle has an area proportional to a specified dimension of the data.

## What is the bin width of a histogram?

Multiply the number you just derived by 3.49. The value 3.49 is a constant derived from statistical theory, and the result of this calculation is the bin width you should use to construct a histogram of your data. In the case of the height example, you would calculate 3.49 x 0.479 = 1.7 inches.

## How do you find the height and width of a histogram?

To draw a histogram for this information, first find the class width of each category. The area of the bar represents the frequency, so to find the height of the bar, divide frequency by the class width. This is called frequency density.

## Why is it called a treemap?

This is so because the Map interface is defined in terms of the equals operation, but a map performs all key comparisons using its compareTo (or compare) method, so two keys that are deemed equal by this method are, from the standpoint of the sorted map, equal.
