Meadows: A Tiny Language That Brings Stock-and-Flow Diagrams to Life
Meadows – a small language for stock-and-flow diagrams that run
Meadows is a small language for building stock-and-flow diagrams that actually run. On Hacker News, a commenter noticed the behavior-over-time graphs fail to render for the hunger, chicken-and-egg, burnout, and predator-prey examples. Creator jjsalamon explained that those early examples have no units attached, so there is nothing to plot, though the system itself still renders; later examples add numbers to stock and flow nodes, populating both graphs.
There's no units attached to those first examples so in effect there's nothing to render in the behavior over time graph. The system can still be rendered however.
