A renderer is a Java™ class that helps to manage the graphical representation of your business data.

Rogue Wave® JViews Diagrammer supplies many predefined renderers. Several renderers are usually active at the same time.

The StyleSheet renderer is responsible for creating and customizing graphical objects and is always active. The GraphLayout renderer applies a layout algorithm and is often active.

Other renderers are created by the SDM engine if they are explicitly enabled in the style sheet.
