Methods, systems and computer readable media for visualizing a collection
of graphs, wherein each of the graphs may be aligned along one axis of a
visualization. All graphs are aligned with respect to the one axis. At
least one metadata value per graph is aligned in a first form of
representation with each graph, respectively. Visualization of the graphs
are compressed in a direction along a second axis perpendicular to the
first axis, and visualizations of the metadata values aligned with the
compressed visualizations of the graphs are represented graphically.
