As the name suggests, cluster web graphic organizers help present clusters of some relevant items in a straightforward way. In most cases, there is a central entity, which the clusters belong to. However, a central entity is not a must in some cases as long as the graphical presentation is totally meaningful to the audience with its proper connection. Different levels in a cluster are colored in different colors. Hence, when you look at such a graphic, you can easily determine which of them are at the same level in different clusters. In some of these designs, pictures of the elements are also included to make things easier.
