Intersection matrix of any two facets (e.g. programs and occupations). Data is returned as a matrix. employed_in_field_pct and value links create the contents of the intersections between the two facets (the sources and targets nodes). The employed_in_field_pct values refer to the degree to which the alumni are employed in field (e.g. value of 1 corresponds to 100% employed-in-field). The value values refer to the number of profiles shared between the two facets. Look at the account meta to get a list of available facets.
