public interface VisualItem
extends Tuple

Base interface for representing a visual item, a data object with a visual interactive form. VisualItems are Tuple instances, and so can support any number of data fields in a backing data table. VisualItems also support data fields specific to visualization, such as a location, bounding box, colors, size, and font. The VisualItem interface provides convenience methods for accessing these common visual properties, but the underlying mechanism is the same as any Tuple -- data stored in a tabular format. Just as all Tuple instances are backed by a data Table, each VisualItem is backed by a VisualTable. Additionally, each VisualItem is associated with one and only one Visualization.

VisualItems are only responsible for storing their visual data properties. The final visual appearance of an item is determined by a Renderer, which contains instructions for drawing the item. The Renderer to use for a given item is decided by the RendererFactory associated with the item's backing Visualization.

Finally, actually setting the visual properties of VisualItems is commonly done by the many Action modules available for processing visual data. This includes spatial layout as well as color, size, and font assignment.
