public class DefaultVisualization
extends TableProxy
implements Visualization, ChangeListener

Base class for concrete visualizations.

This class implements a set of services useful for all the concrete visualizations.

A DefaultVisualization needs a Table. It implements a visualization technique and manages the rendering and interaction with the items.

It interfaces with four subsystems:

1. The Layout subsystem,
2. The Item Renderer subsystem,
3. The Interaction subsystem,
4. The Rulers subsystem.

By default, the Layout is specific to the concrete class. The getLayout() method returns the used Layout object or null if the visualization doesn't need one. For example, ScatterPlotVisualization has no Layout associated whereas TreemapVisualization uses one. Specifying the Layout is visualization specific.

Item Renderers are used to render each visualized items. They form a tree described in ItemRenderer. This tree can be specified in the constructor of a visualization or is created through an ItemRendererFactory.

Item Renderers passed to a visualization can be prototypes or instances (see ItemRenderer.isPrototype(). When a prototype is passed, it is instantiated by the visualization. Otherwise, it is used as it is.

The interaction subsystem is meant to associate a VisualizationInteractor to a visualization. These objects manage the standard event management of the visualizations. When no VisualInteractor is associated with the visualization, then it has no interaction (at least through this mechanism).

The Rulers subsystem provides a mechanism to associate tick marks, rulers and labels to visualizations. Each visualization has to maintain this association when it makes sense. Scatter plots use it to define the axes rulers. The method getRulerTable() returns a Table containing the items to visualize as rulers, as described in RulerTable.
