Interface & Canvas Graph Layout
You can change the letter colour and size for both Entities and Links in the Graphics Settings menu, accessed at: File -> Edit Settings -> Graphics Settings.
Click on the 'Pick Colour' buttons to open a colour picker palette prompt.
You can change the way the nodes are laid out on the graph by changing the 'GraphLayout' setting, accessed at: File -> Edit Settings -> Program Settings.
The 'Dot' layout is a hierarchical tree, the 'sfdp' and 'neato' layouts form circular patterns. Note that 'sfdp' is not available on Windows.
