The node counts the co-occurrences of all value pairs between the group and pivot column. If an aggregation column is selected, the value between the co-occurrences is computed based on the selected aggregation method. In the resulting pivot table, the possible values of the group column appear as row IDs and the values of the pivot column as column names. The value in each cell of the table is the aggregation value, either the number of occurrences or the computed aggregation value.
