1. I noticed the interactive slider, embedded into the webpage. That's not what vanilla Mma 9 can do. Is there a simple way we can do the same without the CDF plugin (e.g. a package I'm not aware of) or is this future functionality?
2. The graph with the migration data looks nice. Mma 9 can't do an edge layout like this (curved edges) by default. Is this again custom code (custom Graphics or custom EdgeRenderingFunction) or is it future functionality?
3. There's the part with the frequency of various graph motives (the number of edges, triangles, and other weird shapes in graphs). How did you count these? Was it done using Mma? Some of these motifs are easy to count (there are simple expressions in therms of the adjacency matrix), but some others like the (1-2, 2-3, 1-3, 3-4) subgraph are not so easy.
4. How did you make the word clouds? Is the algorithm written in Mma? Here's a nice but slow one (the worse answer by myself): http://mathematica.stackexchange.com/questions/2334/how-to-c...
