Nodes within the graph are mathematically clustered together based-on their relationship with other nodes. The weight of the link (line between nodes) is based on the magnitude of the relationship. Force-directed graphs are particularly effective for visualizing how various entities (dimensions) are connected to each other.
This diagram requires 4 dimensions and 0-1 measures. It was built using the D3 visualization library.
