Dynamic graphs can be visualized with aggregated views, where all the graphs are dis-
played at once, merged views, where all the graph s are stacked above each other, and with
animations, where only one graph is shown at a time, and morp hi ng is used when chang-
ing be tween graphs (f adin g in/out vertices and edges that appear/disappear). When using
the animation/morphing approach, it is poss ib le to change the balance between readabil-
ity of individual graphs and the overall mental map preservation, as in the system for
