In the process of diagramming systems, whether a hydroponic system or the ability to concentrate and do work, I have found myself continually in need of a better means to represent relationships and system components. Although Meadows’ stock and flow diagrams are relatively easy to understand for simple systems, I am beginning to feel as though even a step beyond straightforward feedback loops demands reinterpretation and re-representation. There are many intricate and complex relationships even in relatively simple systems, evident perhaps in my apparent need to add pluses and minuses to the diagram above and my inability to fully pursue the interrelationships of farming systems in the previous post, which arose partly due to a desire to avoid an illegible network of lines and arrows that would have demanded finger-tracing to follow. Instead, I am beginning to wonder whether arrows and inputs and outputs are enough, and am interested in applying what I recently read of Tufte’s work. Mapping systems, surely, comes under the realm of the information graphic, and his recommendations are worth further exploration.
