When working on your diagram, you may have to move your content around your canvas, as you add more elements, further expanding it.
Let’s take a mind map as an example. As you add more branches, you may need to space out your mind map, to avoid leaving closed spaces.
The easiest way to move your content would be to make a selection of parts of your diagram and then manually move it around to space it out further.
