Description

TSimpleGraph is a visual Delphi component, which provides a canvas for drawing simple directed graphs.

The control has the following predefined node types for basic geometric shapes:

• Triangle
• Rhomboid
• Rectangle
• Rounded Rectangle
• Pentagon
• Hexagon
• Ellipse

By overriding one or two methods, a new node type can be derived easily from one of the existing node classes.

The control has one predefined link (edge) type. Each endpoint of a link can be anchored to a node or another link.

The repository contains the source code of a Delphi application, which demonstrates the features of the TSimpleGraph control in action.

See the documentation for details.
