Sorry… I didn’t mean to imply that PlantUML or Mermaid had any accessibikity support out of the box. I’ve not tested it and wouldn’t expect it to do that.

My point was more that the raw Marmaid “code” is more likely to communicate the content of a flow chart to some users with certain access needs than a diagram made of divs. In the same way that raw HTML, or HTML rendered with no stylesheet is (should be) more accessible than a document with accordions and carousels.

I accept there probably isn’t tooling to turn Mermaid into a more accessible diagram yet. But there could be. If instead you transmit the diagram as HTML with CSS hacks, you’re losing all the semantic data through the informality of the solution.

I left my contrarian comment because fancy demos have a habit of turning into justification for further “clever” but flawed work. A naive user might see the flow chart example as “good” andnpropose they use the hack in their own project. The solution prevents certain groups of people from accessing the data.

Saying it another way: hacks shouldn’t be used to endorse a new technology.
