TSimpleGraph is a visual component, which provides a simple user interface for drawing graphs. The control and its graph objects are fully customizable in the way that let you create almost any kind of graphs. Currently the control has seven node objects for basic geometric shapes: Triangle, Rhomboid, Rectangle, Round Rectangle, Pentagon, Hexagon, and Ellipse. In addition, by sub classing a class and overriding one or two methods, you can provide your own desired nodes. The line (link) object of the control is very flexible, and can be hook to other objects or connect them together.The control has also some methods for supporting Delphi's clipboard and printer objects.
