A Bestiary of Networks

I'm starting to use a very cool program called Graphviz to profile my code and visualize the references made between plans, sections and details in large sets of construction drawings. Graphviz contains several algorithms for laying out networks of nodes and edges. The most interesting ones simulate physical forces across the network (force-directed graphs, or spring models, as demonstrated in this d3.js demo).

Check out this gallery from the University of Florida and AT&T Research. It has twenty-five hundred force-directed graphs. [Link]

Below is a mesh of a helicopter:

And here it is as a spring model:
