network layout

Understanding the complex system of market interactions as a complex network (see http://arxiv.org/abs/0902.0878 ).

Visualization of an ownership network layout process. The algorithm balances attractive and repulsive forces between nodes [1].

Nodes are shareholders or stocks in the Canadian stock market, and arrows represent shareholdings [2]. The size of nodes represents the firms market capitalization value. The width of the arrows is proportional to the percentage of ownership.

The network has a "bow tie" topology [3] and is located in a connected component of the market: green nodes are incoming, blue nods outgoing, and the pink nodes form the strongly connected component.
