The main distinguishing feature of a treemap, however, is the recursive construction that allows it to be extended to hierarchical data with any number of levels. This idea was invented by professor Ben Shneiderman at the University of Maryland Human – Computer Interaction Lab in the early 1990s.
An example of waterfall charts. Here, there are 3 total columns called Main Column1, Middle Column, and End Value. The accumulation of successive two intermediate columns from the first total column (Main Column1) as the initial value results in the 2nd total column (Middle Column), and the rest accumulation results in the last total column (End Value) as the final value.
Treemap: Treemap: size; color; Is a method for displaying hierarchical data using nested figures, usually rectangles. For example, disk space by location / file type; Gantt chart: Gantt chart: color; time (flow) Type of bar chart that illustrates a project schedule; Modern Gantt charts also show the dependency relationships between activities ...

WinDirStat is a free and open-source graphical disk usage analyzer for Microsoft Windows.It presents a sub-tree view with disk-use percentage alongside a usage-sorted list of file extensions that is interactively integrated with a colorful graphical display (a treemap).
A full m-ary tree is an m-ary tree where within each level every node has 0 or m children. A complete m -ary tree [ 3 ] [ 4 ] (or, less commonly, a perfect m -ary tree [ 5 ] ) is a full m -ary tree in which all leaf nodes are at the same depth.
It is free for all uses, but donations are suggested. [2] No source code is available. Notable features include: A treemap represents how disk capacity is allocated. [4] Filters (based on file name, age, size, etc.) enable the user to focus the visualisation on files and folders of interest. [4]
Hilbert R-tree, an R-tree variant, is an index for multidimensional objects such as lines, regions, 3-D objects, or high-dimensional feature-based parametric objects. It can be thought of as an extension to B+-tree for multidimensional objects.
