It is. In addition, many of such visualization techniques not only present a calculation result by a computer to a user, but also promote understanding or discovery of the user through interactive operation with the user. For this reason, a visualization technique for presenting an appropriate amount of information from a large amount of information is important, and various ideas have been devised.
[0003]
For example, the importance is set for each of the relationships between information elements in a plurality of pieces of information, and information having a relationship where a high degree of importance is set is displayed separately from other information, so that the designer can display the information. In some cases, it is possible for a user to select a relation of information to be displayed according to a set importance (for example, see Patent Document 1).
