This repository is no longer actively maintained.

I no longer work with Delphi and therefore cannot provide updates, bug fixes, or support for this project. The code is kept here for reference and historical purposes only.

Feel free to fork the repository if you find it useful, but please be aware that no future changes are planned.

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.
