The two structures can be visualised as graphs in a Java Swing application window. A layout algorithm attempts to place the nodes and edges as readable as possible but modifications to the layout can be done by dragging nodes. The display can also be zoomed and moved using key commands. Some figures in this publication have been created using the Scaffold Generator GraphStream display (Figures and). While this visualisation was helpful during the development process for visual inspection and debugging, it is not considered powerful enough for real-world use cases and will most likely not be part of a CDK integration of Scaffold Generator. A scaffold hierarchy visualisation tool that might sprout from Scaffold Generator as a separate project would have to be very interactive, i.e. zoomable, draggable, and collapsable. Especially scaffold networks tend to grow very fast with the number of included molecules. Therefore, their display needs to be limited in a comprehensive way, e.g. by only visualising islands of active scaffolds as proposed by Varin et al. . Scaffold trees can become big as well, but they have the advantage that one can look at only one tree out of the forest at a time since they are disconnected.
