Intro

Often links have weights that change over time.

The dataset in these examples is Newcomb Fraternity dataset, downloaded from CAOS and converted to JSON by a short Python script.

These 15 matrices record weekly sociometric preference rankings from 17 men attending the University of Michigan in the fall of 1956; data from week 9 are missing. A "1" indicates first preference, and no ties were allowed.

The first two visualizations in this sequence of examples shows the ratings from each week; the remainder focus on the ratings in the first week.

Unlike the example visualizations comparing edge weights, in these visualizations each cell of the adjacency matrix shows only the edge weights in one direction.
