Using GELO to visualize software systems
Steven P. Reiss, S. Meyers, C. Duby · 1989
GELO is a package that supports the interactive graphical display of software systems. Its features include built-in panning and zooming, abstraction of objects too small to see, pick correlation, windowing, and scroll bars. GELO creates a hierarchy of graphical objects that correspond to the components of the structure being displayed. Five flavors of graphical objects are supported, including those for simple structures, tiled layouts, and graph-based layouts. This framework is powerful enough to handle a wide variety of graphical visualizations, and it is general enough that new object flavors can be smoothly integrated in the future.
