Energese Gives Odum’s Strange Symbols a ggplot2 Vocabulary

Field notes

The package maps ten canonical Energy Systems Language symbols into named ggplot2 layers, with ordinary aesthetics such as x, y, fill, colour, alpha, and linewidth plus width, height, or radius controls. A supplied plot_energese_reference() function reproduces the full symbol chart, while the example composes a solar-food-web sequence containing sources, flows, storages, consumers, producers, switches, self-limiters, heat sinks, and transactions. Polygon-coordinate helpers support users who need lower-level custom diagrams.
