This view is drawn by this site from causal-loop-diagram.fbl itself. It shows the data in the document, not the notation the diagram draws.

Bindings of causal-loop-diagram.fbl. Flowchart of the bindings in causal-loop-diagram.fbl: 1 binding(s) (cld) as boxes with the files they claim and their body's format family, and 5 element rule(s) and 0 relation rule(s) as rounded boxes with the type each produces.

  "doc": "The causal loop diagram's .cld body (definitions/diagrams/causal-loop-diagram.dis, causal-loop-diagram.md): the lines family, as the standalone module reads it. One statement per line. The header is read as an entry of its own, so a missing or repeated one raises nothing. A link is an element whose ends are reference attributes, so a link with an end that names nothing is kept and reported rather than dropped; its cause and effect names are read again as read-only value slots, which the definition keys the link by. A word after a link's arrow is a quoted run, a weight written as a number, or a bare word without '='; a link with any other word, such as weight=heavy, is not a link. A name may be quoted, and a quoted name may hold spaces. The last rule takes every statement no other rule reads, so it is kept byte for byte and reported on its line. Removing a variable removes the links and loops that name it.",
