Maps are data visualizations that we are very familiar with and which we use on a daily basis be they on our smartphones or on paper. Maps lay out the complex multidimensional real world in an easily understandable dimensional projection. We need similar maps to understand the structure and dynamics of financial markets and infrastructures, replacing geographic distance with measures of association, exposure, flow or correlation. Network Theory provides the foundations for undertanding complex interactive systems. By taking into account links we can make many risk models more relevant to the real works of finance. This has not been done before.
