This is a fork of Mike Bostock's example of a D3,js force-directed gpaph.
Each node represemts a hypothetical project ID. The values attached to the linkages between projects is the correlation multiplied by 100 and rounded to the nearest integer.
For example, a value of 35 represents a correlation of between .345 and .349
