The 4see framework is an Arup initiative to investigate the structure and function of an economy in a resource-constrained world. The framework incorporates fiscal, social, and environmental elements in an integrated approach. Historical time-series data is used to characterise relationships between these elements, which are then used to create future scenarios of investment options that are both economically and physically feasible. A Sankey diagram, where the widths of lines are proportional to size of flow, is a powerful way to show a snapshot of data. This animation introduces the Sankey diagram of 4see data using preliminary data on the Taiwan economy in 2010 as an example in collaboration with the III (the Institute for Information Industries, Taiwan). For more information about the Sankey diagram, see our INSEAD working paper "The 4see Framework: Characterizing an Economy by its Socio-economic and Energy Activities" (insead.edu/facultyresearch/research/details_papers.cfm?id=32065).
