syntax

Proposed input syntax to be converted to diagram images:

Title t "title - description"
Action a1 "action - description"
End e "end - description"

t > a1
a1 > e

This would render something like the following mermaid:

stateDiagram-v2
state "title - description" as title
state "action - description" as action1
state "end - description" as end

title --> action1
action1 --> end

Loading

So two sections:

• icon definitions
• icon connections

But this is subject to change.

terminology

• title - first step of a diagram
• end - last step of a diagram
• action - "do X" non-branching action, basic building block of a diagram
• question - branching step with two possible outcomes:
  • yes
  • no
