OmniGraffle comes installed with 30 stencils. These range from common shapes—much the like one you worked with in your first diagram—to complex shapes for space planning.
The built-in stencils are grouped in various folders or collections—stencil folders. Later in this chapter, you'll learn to add stencils from external sources.
The seven stencils in this group are a collection of ready-made connections, color, and texture fills, font examples, and various shapes.
