Nodes

Diagram nodes have been classified in three broad categories. They have been discussed below:

Line Based Nodes

Line based nodes refer to those nodes that connect two or more nodes in a diagram and generally not forming a closed path. These line based nodes also include connectors, that are used for connecting nodes in a diagram. The Line based nodes in diagram are :

• Line
• Polyline
• Measure Line
• Curve Node
• Bezier Curve
• Spline Node
• Line Connector
• Orthogonal Connector

Closed Paths

The nodes which come with a closed path are referred to closed path nodes. The closed path nodes in diagram are :

• Closed Curve Node
• Polygon

Rectangle Nodes

The rectangle nodes are closed path nodes, whose shape is derived from a Rectangle. The rectangle nodes available are:

• Rectangle
• Rounded Rectangle
• Ellipse
• Text Node
• Rich Text Node
• Bitmap Node
• Metafile Node
