A Network Graph of CRAN package dependencies

published by adam on Tue, 10/09/2012 - 16:51

Continuing on my recent project of making interactive network graphs (on projects where other brilliant people have already done the difficult querying), here's a visualization of the CRAN package dependencies. Sure, the philosophers graph is maybe more interesting, but this is a very real map of people power, too---and maybe as influential in these statistical times.

The absolutely artful data munging here comes from librestats. Check out his post!

Visual Social Network Analysis in R and Gephi Part II

published by adam on Mon, 10/01/2012 - 00:05

Resuming from last time, I've made some updates to the philosophers' social network including publishing two interactive maps. Quick introduction: you know that sidebar on wikipedia where it tells you someone was influenced by someone else, linking to them? These graphs are generated from asking wikipedia for a comprehensive list of every philosopher's influence on every other. There are some sample-bias issues and data problems I went over in the first part of the series, but overall it's both beautiful and interesting.

Interactive visuals

The first lets you zoom dynamically and makes it easier to see local networks. When you hover over individual philosophers, those who are not linked to them or from them disappear. This uses a tool called sigma.js.
