Using the Diagram Panel

The 'Diagram' panel contains a set of facilities for creating and managing diagrams and the elements they contain. Diagrams are a powerful way of presenting and visualizing a model's elements and their connections. They can be enhanced by a range of overlays that transform the diagram into an expressive view such as a Kanban board, a Roadmap diagram, or swimlanes, which allow elements to be allocated to different aspects such as responsibility or ownership. A diagram can also be viewed as a list of elements, or as a Gantt chart describing the allocation of resources to the elements.
