Hi all,

Just a quick note to those authoring specifications that need diagrams (swim
lane diagrams, process flow charts, class diagrams, customer journeys, etc.).
One of the challenges of having diagrams in specifications is keeping them up
to date as the specification changes. Another challenge is ensuring that the
diagrams continue to be accessible.

There are usually a fair number of diagrams in CCG use cases documents as well
as specifications.

There is a diagramming tool called mermaid.js[1], which let's you describe
diagrams using text (similar to Markdown). The tool then takes the text and
renders a visual representation of the diagram.

I've put together a plugin for our specification authoring environment
(ReSpec) that enables us to embed these text-based diagrams in our use case
and specification documents. The result is a dynamically rendered diagram that
is more easily kept up to date with the specification. In other words, you no
longer need to use a separate image/diagram editing program to create diagrams
for specifications (though, you still have that option if you want to go that
route). The downside here is that you will need to learn mermaid's markup
language[1], which is fairly easy to pick up. There is also a live editor[2]
that helps you see what you've marked up.

We've started playing around with this feature in the VC API specification:

This is the first experimental release; expect bugs[3], please report them,
and we'll fix them as soon as we can.
