graph community clustering

a force layout where like-nodes cluster together, drawn from static data

now with links! the graph shown is firm.csv from @elijah_meeks's block Networks - Graphs 5, converted to json

this iteration also adds data-driven clusters 🎉

clusters are detected with jLouvain, a Javascript implementation of the Louvain community detection algorithm

an iteration on the block clustered force layout, static data from @micahstubbs which is in turn a iteration on Clustered Force Layout 4.0 from @shancarter
