“…With the increasing scale of dynamic graph data, traditional sequential node-link and matrix-based diagrams fail to display all the graphs in a plane which is space limited (e.g., computer and mobile screen, etc). To address above problems, researches design many techniques to visualizing dynamic graphs such as graph animation [1,11,32], parallel-based node-link diagram [5,14], graph snapshots [6,43], graph navigation [19,25], graph projection [13], set-based graph [34], graph clustering [17,47], and hypergraph visualization [29,41]. For example, animating the graphs according to the timestamps in dynamic graph evolution analysis and structure analysis can reduce the showing space, transferring the time for space [1].…”
