Composite figures are created using multiple separate images or figures that are then pieced together into a single, larger image. Some maps may be considered composite images if figures are layered over or used to create them, as well as multi-part illustrations of ecosystems, for example.
Grouped figures appear placed next to one another in a manuscript and often use sub-labels (i.e., Fig. 1.1a, Fig 1.1b, Fig 1.1c). Such groupings are used to indicate related examples that may have similar features or to show different types of items that all belong to one category.
Timelines are meant to display a list of events in chronological order to help students visualize and contextualize the order and significance of these events. Timeline graphics may be built into the design of the book or illustrated separately.
