Graph Decorator

This demo shows how to use the graph decorator concept to customize the behavior and the visualization of graph items.

As example, this demo decorates the nodes with a port candidate provider that is a combination of the following existing port candidate providers:

IPortCandidateProvider#fromExistingPorts: Provides port candidates at the locations of already existing ports.
IPortCandidateProvider#fromNodeCenter: Provides a single port candidate at the center of the node.
IPortCandidateProvider#fromShapeGeometry: Provides several port candidates based on the shape of the node's style.
