The traditional way to plot the assortativity by age is using a scatter plot / heatmap. This is similar to what they did for country homophily on p12 of the Facebook anatomy paper. The result would be a plot with a prominent diagonal, illustrating that "same attracts same".
That aside, imo, Facebook is an incredibly idiosyncratic "app", which makes almost no sense. And yet, it gave us so many opportunities for interesting discussions, like the insights in this blog post. Nice job.
- taliesinb 14y agoYeah, we tried a couple. Those heatmaps I think are quite hard to read.. because it is natural to want to take marginals, but you can't easily do that visually. I think this whole "octile plot" thing turned out quite nicely. It's in a sense a way of 'slicing' the CDF into 8 even strips and projecting them onto a single axis. It's quite intuitive to read, too. Facebook seems to use it too for some of their papers.
