Fig. 4

This is the matrix view of the associations based upon a count of event co-occurrences (data from Bloomington Animal Shelter data.gov). a Shows the discrete variable value event co-occurrences in the rows of the data (csv in this case) as an aggregate count between labels. b Shows the connectivity with labels belonging to the same variable (column) as a result from counting walks of length 2 (taking the square of the co-occurrence matrix). Both subfigures show the challenge of interpreting the data from such a visualization since sparsity, many label numbers, and large value discrepancies create challenges to the viewer (x-axis label names are shortened)
