Treemapping is increasingly becoming a popular method of digital data and information visualization.
Treemaps are simply a display of a set of information/data in a hierarchical structure; a series of embedded clusters, usually geometric forms, coming together to represent a whole. The size, sometimes even color, of one unit (let’s say a rectangle) represents a quantity, a value, or any branch from the data one is trying to visualize.
One of the simplest ways of creating a tree map is using Processing; an open source programming language that offers a simplified, not-so-complicated medium for designers to create images, animations and interactive prototypes.
The tree map deconstructs Mark Twain’s Following the Equator into words– the size of the rectangle then depends on how frequent one word appears in the text.
With some short lines of code a simple yet interesting image that communicates/visualizes the required data was designed.
