Graphical modeling languages require proper management of position, size, and layout. Most modeling editors lack automated support to manage these graphical concrete syntax properties. It is a timeconsuming effort that affects the understandability of the model. Projectional editors prevent end-users from modifying the concrete syntax so they can focus on the modeling task. However, while they offer multiple notations, these editors lack support for graphical languages. In this paper, we present a projectional editor for graphical languages. Our implementation extends the Gentleman editor generator with multiple layouts and interaction-oriented components to generate graphical web editors.
