These diagrams represent how different VotingWorks systems function. They are meant to document systems in a variety of contexts, including:
- The abstract functions or behaviors of systems, ignoring specific parts
- User actions (or activities or behaviors), when they are using a system
- Ideas for design and redesign
- Final designs
- Helping identify failure modes

These are coded with Mermaid.js. Some notes on using this to make/edit/share diagrams:
- GitHub may not support the latest Mermaid.js syntax. TO be safe, use quotes-notation for labeling nodes and connections, e.g.
A["my label"]-->|"connector label"|["another one"] - You can use Mermaid Live Editor to view, export, or modify the charts if they don't show on GitHub.
- You can use Mermad Flow to do the same, but you can also modify the charts in the interactive visualization directly.
