Systems and methods are disclosed involving user interface (UI) search tools for visualizing or summarizing a data set. A number of summarizations may be created that summarizes the data set in different ways. The summarizations may be linked, such that selecting a data element of a first summarization causes display of a second summarization. To assist in linking of summarizations, a user interface is further provided to display suggested linkings between summarizations based on affinities of the two summarizations. Affinities can reflect similarities in the data content of the two summarizations, such as an output of a first summarization being a valid input to the second summarization.
