Diagram Editor Overview
Diagrams and text
The MPS diagrams can be nested into textual editors. Also, individual graphical shapes may hold additional textual information on them.

With the ability of MPS to support multiple switchable editors, diagrams may offer one of several visualizations for your code, together with textual or other notations.
New blocks can be added either by clicking in the diagram or using a keyboard shortcut. Similarly, elements can get deleted by hitting Delete and they may also react to any other keyboard events.
Visual properties persistence
The visual characteristics of the diagrams, such as the layout, size and position of individual components is persisted into the model.
When adding a new element, a code-completion dialog with all applicable types is shown to ease selection.
Dragging the mouse from an output port of a block to an input port of another block will create a new connector between the blocks.
An experimental palette feature allows an easy way to pick the type of element that should be added into the diagram.
Like in textual code, errors in the model get highlighted directly in the diagrams.
The graphical representation of individual elements in the diagram can be customized. A library of pre-defined shapes is available for immediate use.
