Like pyramids, webs and networks organize ideas into meaningful clusters and identify how the clusters are related. Here, however, the design tends to be more freeform and open-ended, with less rigid ranking and with numerous cross links among categories.

This sort of organization, often called clustering or cognitive mapping, is especially useful in hypertext and other forms of electronic writing, but is also helpful in planning and organizing writing that will appear on paper:

Making a Cluster Map is a largely intuitive process. Writers identify meaningful chunks (or "nodes") of information, label the chunks, and draw lines (or "links") to show how the chunks are connected as parts of a unified system ("web").
