Create a note in a diagram by code

Does anyone know what is the method to create a note in a Diagram ? Or how can I create a note in a Diagram by code ? If I well understand, I have to create a Node and set the style of it to Note and then insert it in the concerned diagram right ? But I did not succeed.

Hello
At the top of the Palette, in every diagram editor, you will find tools to add:

  • Notes, which are similar to comments to the diagram
  • Text
  • Representation links, which are notes that allow you to navigate to other diagrams
    Hope it helps

Hello
Thank you for your help but I’m trying to do it by code.
